Atmospheric Monitoring board with BME680 atmosphere sensor and PMS2007 particulate sensor. Uses Adafruit Power Boost and is designed for hand-soldering SMD parts

PCB Board for Quadruped Robot

Puya Py32 Development board. A USB-C port provides power only. The board must be programmed via probes. Contains layout for high speed and low speed crystals.

PCB3_gerber for common mode current meter, a ham radio test tool. KM5HT

This is an accessory that fits the accessory port on the legs of R-unit droids from Droid Depot at Galaxy’s Edge. It is designed to be a holiday tree with three LEDs that will light up like other droid accessories. All through-hole components, 5mm LEDs and ¼ watt resistors, used in the design to make assembly easy. Resistor values are marked on the PCB, although they don’t have to be an exact match. The switch and pin headers are standard 2.54mm pitch which you can usually find just about anywhere online.

The purpose of the switch is to switch between droid accessory sound banks. R-unit droids only recognize blaster and thruster accessories using different resistor values. The switch allows selection of which resistor is used to identify the accessory, thus which sound bank to use when pressing the accessory button on the droid remote.

Happy Holidays!

DIN 5-pin (180°) socket breakout board.

The SuperMem board is an addition to the TRS-80 Model 1k that provides 512KB of Banked SRAM (mostly) compatible with the SuperMem 512 for the Model 1

This is implemented as a small board that replaces the 128 Kbyte SRAM chip on the main board, and contains the 512KB SRAM and the necessary bank control logic.

NOTE: THIS IS FOR V2 OF THE MODEL 1K
