Its a valid point, typically its the "bounce" in voltage whilst balancing is performed which causes the trouble on the serial inputs. This in turn affects the voltage driving the...
Looks like the STM32C0 range could be useful as well
The photocoupler is purely a cost decision - £1.30 for the TLP2358 vs £0.07 for the existing part - gets expensive quickly, for people with 32 cells or more! I'll...
As you can see, I wasn't trying to build the most technically "perfect" or advanced system - it was a trade off between simplicity of build, cost and availability of...
I did look to swap out the opto to a "digital" comms one, however I couldn't find a small part - all the parts I've found (at an ok price)...
From tests I've made, the existing opto works up to about 14,000baud, but that's not 100% reliable. This part also suffers performance as the cell voltage moves up and down....
Ha e you looked at the controller receive circuit, that was modified a while ago to include a MOSFET to clean up the signal, looks similar to this idea. I'd...
I did some experiments with the TLP785 which worked out okay, the 6N136S looks like a good alternative and at 10unit prices of $0.4216 (LCSC) isn't badly priced. Also keep...
Jumping over to STM32 is likely a step to far at the moment for the modules - the amount of testing and re-work on the code would be significant -...
Just going through my parts bins - I've got some 6N137S1(TA) which I brought to try out (supports 10Mbit) however think that only supports +5V operation - and its physically...
