DeviationTx.com Universal transceiver board

This is the SparkFun “Time-of-Flight” Range Finder, a sensor board for the VL6180 distance sensor. A parts list from mouser can be found here

To be clear, this board was designed entirely by SparkFun. You can find the Eagle CAD files on their product page. I simply downloaded their file and had OSHPark make the board without any modifications.

A simple WS2812 RGB LED display.

Simple board with 28-pin ZIF socket and 6-pin AVRISP connector.

2 Zone Controller - ARM KL25 Based - uses a FRDM-KL25Z board as the controller.

Designed to be used with Malibu lighting or similar outdoor 12V lighting systems. In my case the lighting is LED to reduce wattage rating requirements.

Has module sockets for BMP180 pressure sensor, BH1750 visible light sensor, DS3231 RTC/EEPROM, XBee radio, ESP8266 Wi-Fi module, and two LCD modules.

Based off the (working) Takiuino v1, the v2 is a more generic layout which exposes all of the pins available of the 644/1284p chips. Sadly couldn’t keep the board the same width as the other boards in the range (nano, pro mini, pro micro, teensy, etc), this is one 2.54mm pin width wider.

Code soon available (based on the mighty 1284 code)

MarcoBot Version 2

A simple 555 timer based boost regulator.

Simple Teensy 3.1 add-on board to test the relative performance of various state-of-the-art MEMS pressure sensors. Included is Invensense’s 3.5 mm x 3.5 mm ICM20730 7-axis motion sensor with accel/gyro and embedded pressure sensor, Bosch’s 2.5 mm x 2 mm BMP280, ST Microelectronics' 2.5 mm x 2.5 mm LPS25H, and Measurement Specialties' 3 mm x 3 mm MS5637. Broken out are all interrupts (ICM20730 and LPS25H) and all I2C device address bits (ICM20730, BMP280, and LPS25H) to avoid address conflicts. Also broken out is the ICM20730 FSYNC pin to test electronic image stabilization.
