Botbitz TZ85

Well, if you don't want the wait, the single channel FeatherTwos are a good alternative https://nutsandbots.co.uk/product/fe...ingle-channel/

In theory the following Hobbyking ESCs may be able to use the brushed motor firmware that the TZ-85a uses. I'm purely basing this on the fact that flashing the TZ-85a with simonK brushless firmware uses the bs.hex file so any ESC using this file might be able to be converted. Happy to be told I'm wrong though as I'm no expert.

If you want to give it a go, use this link to find out about the pins you'll need to be soldering the programmer to unless you have one of those flash tool pin things I've seen others using.

so this weekend i'm going to take mine apart and see what is going on under there, see if i can trace the outputs to see if it is actually pin compatible at least to the tz, meaning that if the code can be blasted onto it, i know that the pinouts will be the same and hopefully work...

May have to read off the HEX in case i cant get it to work, otherwise i will have killed it! lol

So long as it's AVR (AtMega8 essentially in most ESCs) then even if no existing SimonK hex file is appropriate, working out the pinout isn't too difficult. I did this for the new Red Brick PCBs before discovering that somebody had beat me to it - so if it is AVR based we can definitely get SimonK onto it.

By that logic, getting brushed firmware that can run it can be done by modifying the source for the existing brushed conversion software.

PS I have done this with F-20A to get them to run brushed motors so it is definitely possible!

Or just say F to it and get FeatherTwos instead

I found this in the BLHeli documentation - the left hand picture looks like a match for the picture Ocracoke posted earlier in the thread. This is the same ESC by the looks of it, just the 45A version.

Following that trail I then found this for the underside of the 65A variant, for those not brave enough to take one apart:

Conclusion: it's SiLabs MCU based, and ultimately that means no use of the existing TZ85A Brushless firmware or SimonK, both of which are only Atmel AVR MCU compatible
