This PCB is made to fit the [Nucleo-F103RB](http://www.st.com/en/evaluation-tools/nucleo-f103rb.html) development board from STM. Features: - 64 LED driving stages -- 3.36 A and 26 V max. input (0.05 A per stage results in 3.2 A) -- 0.1 A max. per stage +- 6.4 A and 24 V max. input (0.1 A per stage) +- 0.2 A max. and 350 mW dissipation max. per stage - 10 Bit DAC to steer the driver - Optional potentiometer to steer the drivers - Control-loop for constant current - Feedback amplification to get a high current resolution - I2C header - SPI header -- 2 rotary encoder and 1 tactile switch +- 2 rotary encoders and 1 tactile switch ![3D Preview from KiCad (2).](https://github.com/m3x1m0m/ecthing/blob/master/pcbs/extension_board/output/3d_pic_2.jpg)
