Avionics Bay
The avionics bay sits inside the rocket body and handles all onboard data acquisition, logging, and transmission.
| Component | Role |
|---|---|
| ESP32-S3 | Flight computer (main MCU) |
| MPU-9250 | 9-axis IMU — accelerometer, gyroscope, magnetometer |
| BMP-280 | Barometric pressure & altitude sensor |
| NEO-6M | GPS module — position, velocity, heading |
| SX1278 | LoRa radio transmitter (long-range telemetry downlink) |
| MicroSD + module | Onboard data logging (flight backup) |
| 18650 × 1 cell | Battery power |
| 1S BMS | Battery management & protection |
| MT3608 | Boost converter (voltage regulation) |
Ground Station
The ground station receives telemetry from the avionics bay and bridges it to the PC software.
| Component | Role |
|---|---|
| ESP32-S3 | Ground receiver MCU |
| SX1278 | LoRa radio receiver |
| OLED display | Real-time avionics bay health monitoring |
| USB cable | Data bridge to PC software |
