This is another version of the popular Attiny85 Arduino compatible Development Board, originally released by Digistump.
This version here comes with a micro USB port instead of the PCB in the shape of a USB-A plug. This design here is more reliable, and it is safer for your USB port and your computer, since the original design with the USB port shaped PCB can cause short cuts and damage to your computer, if not properly connected.
On Board Controller: ATtiny85 Supported Platform: Arduino IDE (1.0 and newer) Power Source: USB or External (5V or 6-15V) On-Board LDO: 5V, 150mA Built-in Micro-USB: for programming and debugging Input/Output: 6 GPIO with programmable functions (USB, I2C, PWM, ADC) Memory: 8k Flash Memory (thereof 2k for bootloader) On-Board LEDs: Power LED and Test/Status LED
Before you can use this module with the Arduino IDE, you need to download and install the driver and board manager files.
