Copy files to root directory of microSD card (filesystem FAT32), insert into On-board computer (contacts on top) and run the update process.


Do not downgrade firmware that was installed by the manufacturer! You may get a brick


Each device has its own firmware and is updated separately from different menus. It does not matter in what order you update the firmware of the devices. If you have older firmware, you can install the latest firmware at once, without having to install the firmware one by one.
1. Description of the On-Board Computer update menu.
2. Description of the Controller update menu.
3. Description of the uLight update menu.

To check the current firmware version, go to the Device Information menu, each device has a separate menu.
1. Information about the firmware version of the On-Board Computer.
2. Information about the firmware version of the Controller.
3. Information about the firmware version of the uLight.

Experimental logger added.
Fixed many charger glitches, however still have few.
Added soft start to charger and more safe phase detect.
Completely reworked field weakening, now should not have any hard braking after release.
Added minimum speed reference for speed PID.
Added RC PWM control on P1 port (throttle/brake).
Added more logger parameters.
Few important FOC control fixes, DC current should be calculated better under field weakening.
Fixed one weird ultra-rare bug in square mode.
LEVCAN operates on queues now, log time 2x faster when display updated.
Decreased DCi Ki default from 500 to 200.
Slightly decreased FW start point.
Added full debug info export.
Added logger mode selection and tuned logger start.
Removed first line from log for easy datazap upload.
Throttle / brake curves added (8 point configuration) with presets.
PAS extra scale added for additional modes.
Soft acceleration for cruise added, more shutdown triggers.
Cruise logic updated - phase current limited by selected mode, not throttle position.
Minimum cruise speed - limits cruise activation.
Cruise increment/decrement - control cruise speed with buttons ( port = CR+/CR-)
Cruise restore - recovery last saved cruise speed with button, activated only above min cruise speed. (port = CRr)
Power limit added to modes and battery configuration. 0 = power limit disabled.
Small menu fixes.
CAN inputs increased to 16.
Parameters export / import fixes.
12V shutdown fix.

Big menu update
Control logic completely reworked for future compatibility with BMS
New default values for PIDs
DC-DC low voltage difference charge fixed
Inverted brake input added

Button/switch select for usual speed select input
Save CRC calculation fixed
New speed mode - neutral
Speed increment and decrement added
Added t-sensor NTC 10k B:3380

Fixed brake glitches
Current measuring fixes for better measuring on 6F board
When enable button configured controller will not turn-on anymore when power applied
Autodetect improved, more informative, short-circuit detect added and timeout fixed
Added lock-at-turn-on, will lock throttle untill password on-screen is entered
Voltage on phases detect added, will lock controls
UVLO added

Export configuration (or make screenshots), after controller update do “Erase data storage” and reboot. Configuration will not be imported fully, some values will need to enter manually.
