SparkFun Big Easy Driver Kit is ideal for robots, automatic dog doors, and moving platforms. The Big easy driver kit can drive up to a maximum of 2A per phase of a bipolar stepper motor. This driver is a chopper micro-stepping driver that defaults to a 16 step micro-stepping mode. The...

Seeed Studio has just released the highly anticipated addition to the XIAO series, Seeed XIAO BLE – nRF52840, a powerful Bluetooth LE microcontroller supporting multiple protocols including Bluetooth 5.0, NFC and Zigbee. What’s so special about it?  Seeed XIAO BLE and the...

A number of AI boards have reached the hardware market for DIY and makers in the past years but none seem to be as flexible as the UDOO KEY. The UDOO KEY is an UDOO-Italy newest launch created with both Raspberry Pi RP2040 and ESP32 on a single board for flexible AI solutions. The...

China-based hardware company, LattePanda, has just made known its newest release called the LattePanda 3 Delta computer -- an enhanced version of the previous LattePanda Delta. The LattePanda 3 Delta is a pocket-sized hackable computer just like the previous version, except that it is...

This is a 3 Digit 7-segment display project that contains 3 x Common Cathode displays, current limiting resistors or each LED segment, 3 x PNP Transistor on each common cathode for multiplexing etc. The project works with 5V TTL signals but can be optimized for 3.3V operations by...

Simple UPDI programmer for tinyAVR, megaAVR and AVR-Dx microcontrollers with voltage selection switch (5V and 3.3V). The programmer works with pyupdi as well as with the Arduino IDE as "SerialUPDI with 4.7k resistor or diode". It is based on the USB-to-serial chip CH340N. SerialUPDI...
