Hello,

I intend to modify my G940 Throttle as MasterTec did. I have an BU0836 but I could buy an Arduino board.

My BU0836 sometimes gives me some problem and windows does not recognize it. It is easily solved by removing the device and adding it again.

Initially I will only use 7 axes (3 of pedals and 4 of the throttle) and maybe some pushbutton or lever.

What card do you recommend? What are the advantages and disadvantages of each?

Thanks in advance

Internet
BU0836A disadvantage = (Relatively) High cost, little customization - can disable unused axes.
BU0836A advantage = Ready to use, just "plug and play" smile High (relative to Arduino) axes resolution (12 bits - 4096 points)


Arduino disadvantage = Not ready to use, need flash firmware (theoretically an 5 minutes job), choose parameters. Low (relative to BU0836A) axes resolution (10 bits - 1024 points), can be increased for 14 bits with external ADC (MPC3202/8).
Arduino advantage = Low cost, customization with available ready to use code (e.g. MMjoy2, EJoy32) or user developed code (require code knowledge).
Firmware support TLE 5010 "magneto resistance" sensor, in digital mode.

I have used both in the past, both do the job well, just mater of preference, convenience.

But since you already have an BU0836, use then.

I really I have the "simple" BU0836, 10 bits resolution. Anyway I think I´ll use this smile.

Rectify :),

I think I'll buy a Pro Micro clone. It has the same accuracy as my BU (10 bits), but it seems smaller and more economical.

I have another question, is this Pro Micro compatible with the pots of the G940 Throttle? (I do not know what the value of these pots is, 10k, 100k ...)

Thanks very much
