Electronic modules


Our electronic modules are pre-assembled circuit boards providing specific functions that will serve as components in a larger system. To create a complete application system you will normally have to add other products besides the module.

Modules are a very convenient way of creating products in small series, and of course also for experimental and educational use.

Documentation can be dowmloaded for most modules from the product page and/or manufacturers home page.

To comply with CE regulations (e.g EMC and LVD) you would normally have to put the module in a suitable enclosure and connect it to a sufficient power source. Other measures may also be required.

  Venus GPS with SMA connector
This is the latest version of our Venus GPS board; the smallest, most powerful, and most versatile GPS receiver we carry. It's based on the Venus638FLPx, the successor to the Venus634LPx. The Venus638FLPx outputs standard NMEA-0183 or SkyTraq Binary sentences at a default rate of 9600bps (adjustable to 115200bps), with update rates up to 20Hz! The Venus638FLPx also allows for limited on-chip logging (check out the firmware below), as well as external logging using a SPI flash memory chip (not included). This board includes a SMA connector to attach an external antenna (required and not included, see the related items below), and headers for 3.3V serial data, NAV (lock) indication, Pulse-Per-Second output, and external Flash support. We've also provided solder jumpers to easily configure the power consumption, boot memory, and backup supply. This board requires a regulated 3.3V supply to operate; at full power the board uses up to 90mA, at reduced power it requires up to 60mA. We've made it easy to connect an external battery or super capacitor to the board, to support very fast restarts after power is removed. There are even pads on the bottom of the board for the 0.2F supercap (not included but you can find it in the related items below), which will keep the board hot-startable for up to 7 hours without power! Note: We've broken out the pins for the Venus638FLPx's second serial port (RX1,TX1) and I2C interface (SDA,SCL). However, these ports are not used by the stock firmware. SkyTraq offers an SDK allowing the creation of customized firmware; contact them for details. Features: Up to 20Hz update rate -148dBm cold start sensitivity -165dBm tracking sensitivity 29 second cold start TTFF 3.5 second TTFF with AGPS 1 second hot start 2.5m accuracy Multipath detection and suppression Jamming detection and mitigation SBAS (WAAS / EGNOS) support 67mW full power navigation Works directly with active or passive antenna Internal flash for optional 75K point data logging Supports external SPI flash memory data logging Complete receiver in 10mm x 10mm x 1.3mm size Contains LNA, SAW Filter, TCXO, RTC Xtal, LDO Single 2.7-3.3V supply Dimensions: 1.15 x 0.7 inches
  Pmod RF1 - AT86RF212 tranceiver 800/900MHz
The PmodRF1 is a radio transceiver that can be selectively configured to operate in the open 902MHz to 928MHz ISM band for use in North America, the European SRD Band of 863MHz to 870MHz, or the Chinese WPAN band of 779MHz to 787MHz. This flexibility ensures that users from many parts of the world can safely use this one product in applications requiring wireless communication. The PmodRF1 features the Atmel AT86RF212, a low-power, long-range radio transceiver. Atmel's partner, Meshnetics, independently verified that the transceiver is capable of communicating at a range of 6km, but the effective range will depend on a variety of factors, such as antenna selection, line-of-sight, and other environmental obstructions. The board also features an SMA connector, which allows users to select the antenna that best suits their application. Operates in selected frequency ranges within the North American ISM band, the European SRD band, and the Chinese WPAN band Features a standard SMA connector for use with a wide range of antennas (2" antenna included) Small size (1.5" x 0.75") Ships with a 6" 12-pin cable, a 6" 2x6-pin to dual 6-pin cable, one 12-pin header, and two 6-pin headers

  Bluetooth Modem BlueSMiRF Silver
The BlueSMiRF Silver is the latest Bluetooth wireless serial cable replacement from SparkFun Electronics! This version of the popular BlueSMiRF uses the RN-42 module which has a bit less range than the RN-41 module used in the BlueSMiRF Gold. These modems work as a serial (RX/TX) pipe. Any serial stream from 2400 to 115200bps can be passed seamlessly from your computer to your target. The remote unit can be powered from 3.3V up to 6V for easy battery attachment. All signal pins on the remote unit are 3V-6V tolerant. No level shifting is required. Do not attach this device directly to a serial port. You will need an RS232 to TTL converter circuit if you need to attach this to a computer. Unit comes without a connector. Please see related male and female pins below.

  LED strip driver
The LED Strip Driver with 4-pin Grove interface provides easy connectivity to your standard Arduino device or Seeed Stalker. It can help you control the luminance of a single-color LED strip, as well as the color and the luminance of an RGB LED strip through Arduino. It has 2 terminals and 2 Grove interfaces. The power for the LED strip comes in through the 2-pin terminal. And the LED controlling voltages output through the 4-pin terminal. The 2 Grove interfaces are respectively screen-printed IN (for controlling data input) and OUT (for controlling data shared with the next strip driver). It can drive an LED strip 1 to 2 meters long with 9 V, while 1 to 5 meters long with 12 V. The driver in conjunction with the colorful LED strips can add a wonderful effect to indoor or outdoor usages. Features Grove compatible interface Can be cascaded for a larger display Best results achieved with LED strips 5 meters long or shorter Outputs PWM signals 256 gray-levels are adjustable via programming Arduino and MEGA compatible Screw Terminals (power input and control signal output interface)
  Levelshifter 8 ch
Level translator based on Ti TXB0108. Side A: 1.2 - 3.6V Side B: 1.7 - 5.5V Bi-directional Tri-state output VCCA must be lower than VCCB Not recommended for I2C as the pull-up resistors cause problems with the automatic direction sensing.
  PowerBoost 500 Basic - 5V USB Boost @ 500mA from 1.8V+
PowerBoost is the perfect power supply for your portable project! This little DC/DC boost converter module can run from 1.8V batteries or higher, and convert that voltage to 5.2V DC for running your 5V projects. Like our popular 5V 1A USB wall adapter, we tweaked the output to be 5.2V instead of a straight-up 5.0V so that there's a little bit of 'headroom' long cables, high draw, the addition of a diode on the output if you wish, etc. The 5.2V is safe for all 5V-powered electronics like Arduino, Raspberry Pi, or Beagle Bone while preventing icky brown-outs during high current draw because of USB cable resistance. The PowerBoost 500 has at the heart a TPS61090 boost converter from TI. This boost converter chip has some really nice extras such as low battery detection, 2A internal switch, synchronous conversion, excellent efficiency, and 700KHz high-frequency operation. Check out these specs! Synchronous operation means you can disconnect the output completely by connecting the ENable pin to ground. This will completely turn off the output 2A internal switch (~2.5A peak limiting) means you can get 500mA+ from as low as 1.8V, 750mA+ from 2 NiMH or Alkaline batteries, and at least 1000mA from a 3.7V LiPoly/LiIon battery or 3 NiMH/Alkalines. Low battery indicator LED lights up red when the voltage dips below 3.2V, optimized for the most common usage of LiPo/LiIon battery usage On-board 500mA charge-rate 'Apple/iOS' data resistors. Solder in the included USB connector and you can plug in any iPhone or iPod for 500mA charge rate. Not suggested for iPad (which really needs 1A charge rate). Full breakout for battery in, control pins and power out 90%+ operating efficiency in most cases (see datasheet for efficiency graphs), and low quiescent current: 5mA when enabled and power LED is on, 20uA when disabled (power and low batt LED are off) Great for powering your robot, Arduino project, single-board-computer such as Raspberry Pi or BeagleBone! Each order comes with one fully assembled and tested PCB and a loose USB A jack. If you are powering your project from USB, solder the USB A jack in (a 3-minute soldering task). If you would like to use a terminal block, pick up a 3.5mm 2pin block here and solder to the output spot where the USB jack would go. Or don't solder anything in for a more compact power pack.
