Pimped Alice v56

ST-Link 20 pin to small 10-pin JTAG programming connector.

SE Voltage Reg board

Details: 4Mx9 70ns 30-pin SIMM

SIMM sockets expect a 1.2 mm PCB thickness. OSHPark produces PCBs of 1.6 mm thickness. So this project is only demonstrative as the resulting PCB assemblies will barely fit the sockets.

Provides a selection of 12 logic gates that you can interconnect with patch cables to make a variety of different logic circuits.

Use to break out a microcontroller for your companion bot! New in v4: - Reinforced M3 mounting holes - Moved USB hookup to same end as programming cable (at “head” end)

This board allows the first 32KB of the 8085 CPU, used by the Tektronix 468 storage oscilloscope, to be used with an AT28C256 EEprom. The board requires 6 wires to be connected to the CPU board of the Tektronix 468. Machine level debugging is supported with 4 more wires connected. NOTE: there is an error on the SilkScreen. Where it says “U478-4”, it should say “U478-5”.

Interface DB-9 connector to Sparkfun MAX3232 breakout board (BOB-11189). Connect TTL signals, 3.3 to 5 V, and ground to 4 pins at the edge of the board. Directly plug BOB-11189 into a header, or solder header pins between the boards. No mounting holes.

Flex board that fits under the reflector and centering gasket, notches need to be made in the gasket for the LEDs, a fine soldering iron tip works well for that.
LED : B36S3RGB, resistors : 0402

Add through-hole MAX3232 serial transceiver chip to serial console of a BeagleBone board. Powers BeagleBone from power pads - add screw terminal block or solder wires. RS232 serial output on DB-9 connector, and MAX3232 powered from BeagleBone, so no danger of toasting BB from serial data input. Also breakout board for all expansion pins. Not for stacking capes, but custom hard-wired pins, such as to a connector for a Mesa Electronics isolation board.

Convert any narrow 28-pin IC (0.3") to a 0.6" footprint. I’m using these with Toshiba TC55328 0.3" SRAM ICs to use on the MiniMax8085 which expects 0.6" 62256 SRAM ICs.

Breadboard connector for RFM69CW (and other HopeRF radios) with 3v3 power supply, FTDI connection and breakout for all RFM signals. It uses FlexyPins by SolderParty to the radio can be tested without soldering it to the board.

The ItsyBitsy Breadboard Adapter is an Adafruit ItsyBitsy M4 Express-compatible piggyback module that converts the 3-sided pinout of the ItsyBitsy to dual in-line for use on typical solderless breadboards and soldered protoboards. The adapter was also designed with extra solderable pin connections and mounting ears for permanent installation.

Included is a STEMMA-QT connector that can be optionally configured to connect to the ItsyBitsy’s UART (RX/TX) or I2C (SCL/SDA) signals. A 2-pin JST LiPo battery connection is on-board that supports charging (100mA charge rate), compatible with Adafruit’s standard battery connector polarity.
