Power Supply

Power is supplied to the MCBTSX1001 board from your PC using a standard USB B connector, or from an external 6.5 - 9VDC power supply connected at VIN+ and VIN-.

The voltage regulators (U6) and (U2) generate 3.3 Volts DC for 3V3 and A3V3, respectively. 3V3 and A3V3 may be independently adjusted using multi-turn potentiometers 3V3 SET (R49) and A3V3 SET (R7). The LEDs 3V3 (D12) and A3V3 (D1) indicate 3V3 and A3V3 power is present on the board.
