Transmitter Board parts diagram: 1 bare PCB, 2 microcontroller, 3 GPS module, 4 pressure sensor, 5 barometer, 6 RF transmitter module, 7 temperature thermistor, 8 SMD passive (R/C/L), 9 connector. 99 parts in 9 top-level items. — Transmitter Board parts diagram. Numbers match the table below; each box is one top-level part or assembly with what it contains.

#	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×	Reads sensors, frames telemetry
3	GPS Module	1×	Position and derived wind
4	Pressure Sensor	1×	Air-pressure sounding
5	Barometer	1×	Redundant pressure reference
6	RF Transmitter Module	1×	403 MHz transmitter IC
7	Temperature Thermistor	1×	On-board reference junction
8	SMD Passive (R/C/L)	90×	Surface-mount resistors, capacitors, and inductors, typically in 0402 to 1206 packages, that set voltages, filter noise, and time signals on a circuit board.
9	Connector	2×	Sensor and battery headers
