MMA8652FCR1 Breakout Board using SMT Headers.

6502 CPU Board Rev B. Designed for the RC2014. Board design files are at https://github.com/ancientcomputing/rc2014/tree/master/eagle/6502_board_revb

This is a breakout board for the MCRobbie. Documentation can be found here and is all licensed as CC-BY-SA.

The code is available on GitHub under the Apache2 license.

This version uses a PIC18F14K50 and has space for an 100nF decoupling capacitor for the power supply.

A power control board for a Raspberry Pi used in the VasttraPi project. The board has four USB ports. The first one is used to receive power and power up an ATtiny85 microcontroller. The MCU drives a relay to turn on and off the power to two USB ports and talks UART over the third USB port.

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.

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.
