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

Simple interface to run my Anet A8 using ESP3D and an ESP-01 module. A TTL gate keeps startup serial data out of the printer. Requires removing 2 zero ohm resistors and installing a 6 pin header on the Anet controller in the BLE/USB position. You will also need to add code to the ESP3D sketch’s setup() function to set GPIO 0 as an output and write a logic LOW to that pin in order to enable transmit data to go out of the ESP-01 to the printer. This board should plug in to the connector next to the LCD connector. Power should be taken from the 12v board power (or a separate wall-wart might be used). Given the various problems an Anet A8 has, I didn’t want to stress its on-board voltage regulators with an ESP8266. This is revision 2 of this board, which uses a Recom R78E3.3-1.0 switching regulator. I also brought out GPIO2 to a header so the reset functionality of ESP3D can be used.
