Connection of `RXD` and `TXD` is confusing, should be interchanged (TBD next PCB revision).
## Voltage levels
| Pin | Levels |
| ----- | ----------- |
| `ST`, `M0`, `M1` | 5V (can be changed with R7, R8, R9)
| `TXD`, `RXD` | 3V3 (RXD can be changed with R3, TXD needs level converter)
| `TXD`, `RXD` | 3V3 (input can be changed with R4, output needs level converter)
| `EN` | >2.3V enabled, <0.5V or open disabled
| `PTT` | open-drain, max. 25V
| `AUD` | default 90% volume is ????Vpp to high impedance (>5kohm) load
| `VDD` | ???-16V
| `AUD` | default SSTV audio is 1.5Vpp to high impedance (>5kohm) load
| `VDD` | 3.2-16V (3.1-6V if R31=0ohm, IC6 not placed)
