FOC controller like sabvoton will give you less heat and for the same battery amp increase power specially on start. On high speed it doesnt metter if itc squere wave or sine wave. If you like to have nice display then you can use phone with planty apps that show speed distance etc. For battery...

Try sabvoton. It is with foc. No noise and plenty options. Can connect to phone via bluetoth

Here is connectors information and about display

Btw i never use schematics. I follow traces start from power supplying cables and check everything for blown parts. If not look for transistors or converters beacuse they rearly have visual symtoms.

Hi. Sorry for laye reply. Just pm me because i am not notified for new posts. Just measure first on cables red and black if you get 12v then go to dc-dc converter from your picture and hold one pin of multimeter on gnd(black cable- i belive its marked there as gnd) and other pin near c17...

When program is uploded to arduino and nothing is connected or D2 connected to ground, it still output itself 3v on pin D11. I check it while its connected by usb to laptop and on bike.

You haven't received even one rfid? One is for driving and one for settings changing. I dont think you can make it start from controller. Display is having 5 speed mode, is able to turn on off pas, throttle etc. From what i remember from display come out 2 wires for data. Thats all. Easier way...

How about double mosfets on vesc plus add cooling to have more amps? Gate driver is more about applying volts not amp if i am correct. How about then use any simple 12 mosfets controller. Double its mosfets and use its driver to power them. Can see idea here...

I am trying this arduino board but it starts immediately after turn on bike without any pedal movement. I have tried higher min voltage also. Honya96 If you want connect to single output just add diode on signal wire. Best to add 2 pieces. 1 for arduino and 1 for throttle Edit: I have tested...

Probably because high phase current adjusted. Throttle voltage should build up slowly. I will update you when i am done with arduino board. I am currently working on it. I am also planing to make hidden switch like you or use arduino bluetooth board and control remotely from phone app.

Many thanks to you fkopac i really need this. ZB pin is applying for sabvoton controller or some other one?

For anybody looking for that send to thread for someone who made it already with arduino nano https://endless-sphere.com/forums/viewtopic.php?t=87116

Problem with 555 timer is it can be triggered only by voltage below 1/3 of supply voltage and PAS is giving higher spikes. Maybe can be done by NPN transistor that will switch ground. Not sure if it will work because PAS have standby voltage 0.4v or 0.7 (don't quite remember correct).

I will try to make it short. Idea is for making possible use my ebike legally. Requirement are 250w and PAS(not throttle). I can adjust in phone app 250w. Only problem that Sabvoton don't communicate with PAS without Cycle Analyst. When PAS is moving sensor is sending spikes of voltage. I am...

I have 49. Also mxus v3, gear ratio T5. Try maybe it might help.
