New Band Burner e-Timer – Micro JST Version
The Band Burner e-Timer is a lightweight electronic dethermaliser (D/T) solution for small model builds. It cuts a rubber band or string by heating a Ni-Chrome element after a set time, allowing control of rudders, elevators, or other movable parts.
*Note: Earlier versions (before summer 2023) had 1-second timer steps. Newer versions use 10-second intervals.

🔥 Firmware Update – 03 January 2022
Due to a shortage of high-current batteries, the firmware was adjusted to halve the heater current draw.
- Now compatible with 80–100mAh protected LiPo batteries.
- Heater remains hot enough for elastic bands, but glow may be reduced.
- In extreme cold, performance may be affected.
- If using an unprotected high-current battery, a solder bridge between the designated pads enables full-power mode automatically.
