Describe the node’s purpose, deployment environment (e.g., hilltop repeater, urban mesh extender), and design goals.
- Microcontroller: (e.g., T-Echo, T-Beam, Heltec V3)
- Battery: (e.g., LiFePO4 32700 6Ah)
- Solar: (e.g., 6V 6W rigid panel)
- Power Management: (e.g., CN3791 MPPT)
- Antenna: (e.g., 433MHz fiberglass omni, Yagi for directional links)
- Enclosure: (e.g., IP67 junction box, clear lid)
- Region: ANZ
- Frequency: 915Mhz
- TX Power: 30dBm (legal max for AU/NZ)
- Channel: LongFast/Custom
- Node Role: Router/Repeater/Gateway
- Solar Controller: MPPT (recommended), PWM
- Battery Chemistry: LiFePO4 / 18650 / Lipo
- Autonomy Estimate: X days no sun
- BMS: (e.g., 2S with low-temp cutoff)
- Mounting: e.g., U-bolt to mast
- Location Considerations: e.g., line-of-sight, elevation
- Reliability Measures: conformal coating, drain holes, silicone seals
