Coinkit with simple regulator & using Photon Development Board.

Comms w/ vending machine over the internet. Designed by a complete noob so… hope it works!

Larger Parts for hand assembly

Daughter board for the DDm-K2 driver board.

https://oshpark.com/shared_projects/F9jb3vFP

The switch is a NO SMD 6.2x6.2x3.1 mm tactile type. The LEDs have 0805 footprints. Normally R1 is not populated. A jumper or small-value resistor here wires the two LEDs to be driven in parallel.

5+1 7135 driver for Solarstorm/Fandyfire K2 lights.

Revision changes

• New

Needs the DDm-K2-SW daughter board for the tactile switch and indicator LEDs:

‘Standard’ BLF parts list, except for:

• R1 and R2 are populated if MCU pin 7 is used for cell voltage monitoring. This could, however, be done using the software-only method of Vcc vs. the internal 1.1 V reference.
• R7 is populated when re-purposing pin 7 to drive a second indicator LED, as per the stock driver.
• There is an R1 on the back of the switch board. A jumper here rewires the two indicator LEDs in parallel, both to be driven from MCU pin 3.
• C3 = 10 uF is optional
• C4 = 100 nF is optional

or “Fluxkompensator” as we Germans call it… this is Version 3, with a battery holder and a switch (finally!) Battery holder is for 12mm batteries, holder is the cheapest on ebay. should work with attinyX5 and attiny13. 0805 resistors.

Provides a breakout to the compute/comm PCB connector on the r2-Backplane. It is also useful as a template for a custom Compute PCB.

Intended usage

This project has two purposes:

1) To be used as-is as a signal breakout for using Digitabulum and the r2-Backplane with a new microcontroller without rolling a PCB for it.

2) To be used as a template for a custom compute PCB to be attached to the r2-Backplane.

A 750mw work horse from 9V battery - you can visit DXer.ca and e-mail me for the schematic diagram - a very useful signal trace circuit!

A development board for Xilinx CPLD’s

An SMD adapter converting the proprietary TI 20pin header (found on many of the Beagle Bone boards including the Beagle Bone Black) to a standard ARM Cortex 10pin debug connector, found on the Black Magic Probe and many other JTAG/SWD devices.

Recommended to be manufactured as a 0.8mm thickness PCB.

BOM:

• 0402 1k Ohm Resistor
• FTSH-105-01-F-DV-K 10pin 0.05" pitch connector

This adapter board design is part of the 1BitSquared adapter collection.
