USBasp - USB ISP/TPI programmer for Atmel AVR microcontrollers based on the design by Thomas Fischl. More information can be found at https://www.fischl.de/usbasp/. Windows users may need to install a driver. Of course this is not necessary for linux and mac users. Close SELFPROG and TGTPWR jumper when uploading firmware. If you are burning a fresh microcontroller, close the Slow Serial Clock jump...

Close SELFPROG and TGTPWR jumper when uploading firmware. If you are burning a fresh microcontro...
# TinyICOC - AVR In-Circuit Oscillator Calibrator
Sometimes AVRs are operated without an external clock. The internal oscillator does a good job in most applications, but when it comes to precise timing, its +/-10% accuracy is often insufficient. Fortunately, the oscillator can be calibrated, increasing its accuracy to +/-2% or better. There are a few ways to perform this manual calibration, but s...

EasyEDA project for simple and quick assembly of the "SWR-mouse" antenna analyzer adapted for installation in the [G403 case (Gainta Industries)]. The project includes the "SWR-mouse" antenna analyzer schematic and the PCB file. Version for mounting SMD components.
## Current development progress:
Universal board for LED control.
- Atmega8/328 on board with programming connector
- PCA9685 for 16 channel PWM up to 1.5kHz (eye-safe frequency), 12 bits per channel
- cheap ULN2003 with paired outputs for 1A per channel (2-3 meters of RGB 5050 strip per connector)
- or SOT23 MOSFETs if you need more power
- BT05 bluetooth module or MAX485, control by wire or wireless. DMX512 is possible.
