VILKAS-RX firmware 5.36
Boards: VILKAS-RX Rev B ✅ · Rev C ✅ · Rev D ✅ (firmware ready, no hardware yet)
Protocol: v4.3. Works with every 4.x / 5.x remote; TX 5.36 recommended for all new settings.
The first public 5.x release, with everything from 5.00 to 5.36.
Highlights
- 100 Hz control and quiet 20 kHz motors with slow decay: smoother, more linear driving.
- Failsafe always stops, with a configurable time (250 / 500 / 1000 ms).
- Survives the match: after a brown-out, watchdog or crash the robot is back in ~0.2 s, and the remote tells you why. Gentle direction changes (
Rev Ramp) and a low-voltage power limit (Cut-off) help prevent brown-outs. - New robot settings:
Min Start,Turn,Stop(coast/brake),W Ramp,W Rate(up to 400 Hz),ESC Cal(ESC calibration from the remote). - Phone driving: a welcome page opens on the phone, then the remote runs full screen in the browser. Optional 8-digit Wi-Fi PIN. The paired remote can bring the robot back from phone mode.
- The Wi-Fi updater checks the maker tag (prefix).
- New LED signals: weapon armed, low-voltage limit, unexpected restart.
