[WIP] micro quad [DO NOT ORDER]

Connects a Nrf24 radio to Arduino Pro

Tims LED Board REV 1

Sparky 1.1 flight controller. This is a Tau Labs target that uses an STM32F3 processor and MPU9150 sensor plus an MS5611 pressure sensor. It is capable of altitude hold, position hold, RTH, gimbal control, and more.

916.5 Mhz Radio to BLE Bridge. Designed to communicate with Medtronic insulin pump, CGM, and BG meters.

$12.15/set of 3 (untested/will update)
Adjustable switcher (buck mode) @150kHz - all hand-solderable, durable ground plane construction. Uses an ATX-4pin plug for handy [12v optional] power in & no need to rewire the cable!
Many choices for parts. I bought the LM2595 ICs on a whim; I’ll roll a few and see how it goes.

Modernization of the Apollo Guidance Computer

Pro Mini Arduino based RBG LED Strip Controller

3 DPDT relay board to replace 6PDT relay in Roland S50. Two holes in the middle are for hold-down screws. I recommend putting in sockets so you can replace the relays more easily as they will go out again the way they are being used.

Simple Breakout board for the Bluetooth BLE beacon HM-11

Barometer, magnetometer, GPS and I2C breakout board for CC3D on Cleanflight. You can also plug in an OLED display and GPS. Board size is the same as CC3D (36x36mm), and so is the hole placement (30,5mm apart). Measurements (link to wiki.Openpilot.org) Male headers are meant to be soldered as SMD, except for 3v3 I2C, which is through hole. You can also solder 90degree headers poiting up. SMD jst connectors are on the bottom side, if you dont want to use headers. Pinouts for jsts are the same as their top side counterparts. The direction is marked with “->” sign, poiting towards MAIN and FLEXI ports. Pinouts for MAIN and FLEXI are the same as on CC3D, dont switch rx and tx. If you want to connect it to a computer, you have to plug the battery to power the addon board, otherwise the virtual USB wont show up in Configurator. It works, I still use the prototype board on my big quad. !Make sure to correctly set the port settings!

CIC_KEY_V3.2

Berg40 to DE9x adapter for DEC boards

This is an adapter board for DEC serial boards (DL11 series, KL8 series) that use the 40pin BERG (IDE) 2x20p cable connector for the serial port. It routes the serial signals from the flat cable connector to various pins on the DB9 (M or F) connector thru a set of 100mil jumper header blocks. Flexibility for using either a male or female DB9 connector is provided by using different jumper block positions.

J2 is a standard shrouded 40p male connector.
J1 is either a DB9 female or male connector, as desired.
P1-P4 are a set of header pins for jumpers.

Design files are accessible at this link

These are DipTrace schematic and layout data files; acrobat PDF of schematic and board are provided, as well as full layout gerber and drill files.

I2C Keyboard Lipoly Charger

Accelerometer with Temp Sensor

Filament width sensor based on TSL1401CL linear sensor array and ATtiny85, see http://www.thingiverse.com/thing:699308

A brushed adapter for Sparky or Sparky2 with an integrated 5V adapter and 200mW 5G8 VTX. Unfortunately it uses the TX5200M module which is hard to come by.
