ATMEG32U4 dev board

LambdaSpeak 1.95 is a next-generation speech synthesizer for the Amstrad (Schneider) CPC computers (CPC 464, CPC 664, CPC 6128). More details about the project can be found on the project GitHub page.

Apa102-2020 Micro Board w/dec cap - 603 (47EpJYK9)

apa102-2020 wide edge conn side rounded w/dec. cap - 0603 (rxk7Z3Vg)

apa102-2020 0.3 Space Breadboard w/dec. cap - 0603 (U7D43YSE)

This is for a college capstone project. We are receiving analog signals and processing those through an Atmel chip.

ICSP to ZIF adapter for 8-20 pin DIP ATtinys. Rev 2 has bigger holes for ZIF socket to accommodate “TFXTDOL” knockoffs.

Teensy breakout to drive 4 LCDs (serial enabled).

This is the PC board for the ProjectMF PIC 12F683 Phone Phreak blue box that was given away at the HOPE conference by Phil Lapsley. See http://www.projectmf.org for details.

Right Angle CF-IDE44 Adapter Mounting Board and Shield

Simple(st) and cheap(est) interface for Davis Vantage Vue with v3 software (infamous green dot). Tested with Vantage Vue, should work with other stations too.

IC1 = ATTiny85 with program from : http://meteo.annoyingdesigns.com/DavisSPI.pdf

C1 = 100n (optional)

D1 = 3v3 Zener (optional)

R1 = 470R (optional, short if not used)

J1 = 2x10 female header 2.0mm pitch

Should be used with USB-UART cable (tested with PL2303, should work with others too), B-ground, W-cable’s Tx, G-cable’s Rx. If cable is 5V one, it’s recomended to use R1 and D1 as a voltage clamping since Davis operates at 3v3.

Description Pretty much what the title says. This is a 16.25mm x 22.5mm board for PWM sound to a 3.5mm jack.

TMC2130 Breakout Board with SPI For Trinamic TMC2130. Solder free way to connect your 4 or 5 stepper drivers.

A converter from FFC from the Pi camera to HDMI.

Turtle robot that uses an Adafruit Trinket Pro as MCU. BOM & instructions at https://github.com/aspro648/OSTR

Description

Simple breakout board to convert logic-level signals to CAN bus. The MCP2562 is nothing but a fancy level shifter and must be used with a CAN bus controller, such as a Microchip MCP2515.

This board fits in a breadboard!

The left-side pins are the same as the CAN bus header on the LPCXpresso11C24 dev board.

Designed in EagleCAD.

Pins

Right side:

• TX: data out from CAN bus
• RX: data into CAN bus
• GND: ground (same as left side)
• +5V: powers chip (same as left side)
• VIO: interface voltage reference
• STBY: place the MCP2562 into low-power state

Left side:

• CANH: high-voltage side of CAN bus (usually 2.5-5V logic)
• CANL: low-voltage side of CAN bus (usually 0-2.5V logic)
• GND: ground (same as right side)
• +5V: transceiver power rail (same as right side)
• STBY: place the MCP2562 into low-power state

BOM

• U1: Microchip MCP2562SN
• C1, C2: 0.1µF 0603 ceramic capacitor
• R1: 120Ω 0603 resistor

Description

Simple breakout board for Honeywell’s MPR line of pressure sensors, which use a Wheatstone bridge and an optional 1nF filter capacitor.

This board has 0.5" pin row spacing such that it fits in a standard breadboard.

Designed in EagleCAD.

Pins

Right side:

• RST: reset, active-low
• EOC: end of conversion, data is available, active-high
• GND: ground
• +3.3V: VDD (note: device has no reverse-polarity protection and very little over-voltage protection)

Left side:

• MISO: master-in-slave-out for SPI
• SCL/SCK: clock input for SPI and I2C
• MOSI/SDA: data input for SPI, data I/O for I2C
• CS: chip select for SPI

BOM

• top footprint: any Honeywell MPR device
• 100nF: any 100nF 0603 capacitor
• 1nF: any 1nF 0603 capacitor
