You ve tree wire from throttle and tree from break , all two goes to brain.
The are 5v supplies by the brain ,thé brain itself is supplied by 36v from battery .
You need a new controller with its display from AliExpress .
Cut the throttle and break wire, original brain goes to trash. Re wire all (not the orange connecter from battery , that s i don’t Know ?)
On controller you ve got one 4wire connecter , that s 5v , ground, break and throttle signal..
on controller you ve got a 3big wire that phase of motor, and 5thin wire that are the hall sensor (5v, ground , and tree hall feedback) so hère is thé biggest challenge 3wire motor, that can be switch itself( that done 6possibility) and the 3wire from hall( that done 6possibility too) so 6x6 done 32 possibility just to good wire the motor.. if you done this , the last Step is easy.
My last challenge it s to change thé tree wire from break that give a proportionnal voltage to a two wire switch that give ground to break wire controller .

I hope i ve helped.. To view images REGISTER or LOGIN for full access.
Hi everybody,
Giles99, I need your help.
I don't really understand your detailed message.
I tried to use a Xiaomi M365 board with same wire but it doesn't work and I don't know why... the light work well, I have the battery level too (1 level available of 4), but no light for brake and the motor don't work when I use the throttle ..

Thank in advance for your help ! To view images REGISTER or LOGIN for full access.

Have you managed to change the brain of a dott or not ?

Seems like all the companies have switched to custom built scooters right ?

Gilles,
i've the same model as you. One DOTT model. I've just take the red board and i would like to flash it or to hack it to use the scooter all the time, but and do know how doing on this model.
You said you suceed in with this model by a new red board. Can you help me by explaining me the connectins i have to do ?
Or, if this subject is answered, can you give me the link to help me with a "how to do" connections in the board.
Or can you give me the model you buy on aliexpress and the connections i have to do?
Thanks a lot.

Gilles,
J'ai exactement la même trotinette DOTT avec la meme carte mere...j'aimerais la mettre en service soit en la flshant comme c'est indiqué dans certains tuto, mais je nai rien trouvé pour ce modèle.
Tu expliques dans ton post que tu es parvenu à mettre ta DOTT en service en changeant la carte mere. est ce que tu peux me donner la référence de celle que tu as acheté ou bien le lien d'achat et aussi me donner des explications pour son changement et les connectiques?
Merci de ton aide, car je suis devant la même problématique que toi, à quelques semaines prêt.
A+
