| Name | Description |
|---|---|
| PartialSupplyPin | Supply of a peripheral: optional GND and VCC pins, internal supply rail - GND shown and ideal internal supply VOH by default |
| PartialUartPins | Electrical side of a serial device: TX output and RX input on two pins, common ground, optional VCC pin - shared by the serial devices and the radio modems |
 PartialUartDevice | Base of the external serial devices: electrical link, decoding, two transmission modes, quantities exchanged with the model |
 PartialI2cDevice | Base of the I2C slave peripherals: open-drain electrical link, bus decoding, behaviour described by a Python script |
 PartialRadioModem | Base of the transparent radio modems: serial link with the microcontroller, radio frames on air, buffers, fixed delays, drawn modulated signal |
| PartialTextDisplay | Behaviour of the large text screens: each message received through displayLink is written under the last written line, the screen scrolls up once full |
 OnBoardRadioModem | The on-board 2.4 GHz radio of the micro:bit as a transparent modem: the same engine as Peripherals.Radio.RadioModem, mounted inside MicroBit_v2 on two internal pins of the core (34 = TX of the core, 35 = RX) - the packet protocol of microbit.radio (framing, channel/group/address filtering, receive queue) lives in the Python shim, see requirements.md decision "Radios micro:bit" |
