6 top-level parts · 65 parts in total · full bill of materials below
| # | Part | Qty | What it does |
|---|---|---|---|
| 1 | Bare PCB | 1× | Unpopulated printed circuit board: copper traces etched on an FR-4 glass-epoxy laminate that carry current between the components later soldered to it. |
| 2 | Microcontroller | 1× | TX control + audio framing |
| 3 | UHF RF Transmitter | 1× | UHF modulator + PA |
| 4 | Frequency Synthesizer | 1× | Synthesizer / VCO |
| 5 | SMD Passive (R/C/L) | 60× | Surface-mount resistors, capacitors, and inductors, typically in 0402 to 1206 packages, that set voltages, filter noise, and time signals on a circuit board. |
| 6 | Connector | 1× | Antenna + battery leads |
