Miniscope v4-MCU
Miniscope v4-MCU is an open source AVR/Arduino PCB design by Aharoni-Lab: a 6-layer, 7.5 × 8 mm board with 12 components (6 distinct parts). It is built around the ATMEGA328-MU.
All things Miniscope v4
The original PCB was designed along side the CMOS PCB and SER-Power PCB in CircuitStudio but I wanted to make some modifications to the MCU PCB as well as start porting all projects over to KiCad. The main changes from the original MCU PCB are the following: Added a 50mil 2x3 ISP interface for programming the Atmega328 without the need to solder wires. Changed the output of the board to interface with the dual digital potentiometer used on the LED + ETL Driver PCB.
