Power Modes
Trade CPU and WiFi power for battery life and range
Switch power modes in Settings → Power Mode.
| Mode | CPU | WiFi TX | When to use |
|---|---|---|---|
| Low (0) | 80 MHz | 10 dBm | Battery-backed deployment; long unattended runtime; close-range WiFi only. |
| Normal (1, default) | 160 MHz | 17 dBm | Day-to-day operation; balanced runtime and range. |
| High (2) | 240 MHz | 20 dBm | Maximum WiFi range, fastest script execution; higher draw. |
Power draw (typical)
| Mode | USB current | Battery hours @ 1000 mAh |
|---|---|---|
| Low | ~80 mA | ~12 h |
| Normal | ~150 mA | ~6.5 h |
| High | ~220 mA | ~4.5 h |
Numbers are with WiFi AP active and BLE on. Disable WiFi entirely (Settings → WiFi → Off) to roughly halve current.
Effect on scripts
CPU frequency affects:
- Maximum keystroke rate in
write/writeLn(Low mode caps around 180 chars/s vs. 250+ on Normal). - TraceNetwork heartbeat jitter (Low mode is noisier, ~±30 ms vs. ±10 ms on Normal).
WiFi TX affects:
- AP range (Low ≈ 5 m one-wall, High ≈ 30 m one-wall).
- Reliability of remote triggers and Live mode latency.
The selected mode persists across reboots.
