2.5.5 BFH Mother Board

On the mother board the Olimex STM32H103 board is mounted on. The mother board has a
power supply and drivers for interfaces.
The mother board uses the power supply form the STM32H103 board. Just connect the
STM32H103 with USB and the mother board is powered.
4 LEDs, lighting when tied to LOW (D1, connected with J24; D2-J25; D3-J28; D4-J28)
2 Buttons with a pull-up resistor, pressed gives a LOW state (S1, connected with J2; S2-J12)
1 Serial driver (RS232) (Rx-PA3; Tx-PA2; RTS-PA1; CTS-PA0 if DIPs are set according to
Figure 2.7)
2 potentiometer for analog inputs (R8-PC0; R9-PC1 when J26 and J27 are set)
