Uses ths microconroller

It uses these 3 pairs of DACs

MicroChip 2 MCP4725A0T-E/CH DAC SOT32-6

MicroChip 2 MCP4725A1T-E/CH DAC SOT32-6

MicroChip 2 MCP4725A2T-E/CH DAC SOT32-6

Some SMD components

switches

------------------

BAT85 Schottky Diode 30V 200mA

BAT54ht1-g

using these instead

This could be the problem ????

Remove RX LED

Solder to the Seeeduino ... pad 17

I uploaded the firmware successfully
