Hello,
I plan to buy a8v3 and use it with ESPhome.
But, I would need:
- RXTX (https://esphome.io/components/uart/#uart) ideally on external connector
- 4 Pulse Counters (PCNT, https://esphome.io/components/sensor/pulse_counter/) on external connector
Could you confirm that:
- for RXTX, I can re-assign pins used for Analog Input (AI-1 and AI-2) and map RXTX on it.
Would I lost any other feature (than ADS) from a8v3 in that case (I think that ESP32-S3 is limited to 2 end-user RXTX)?
If that's not possible, can I directly re-use the RS485 connector (for my RXTX pins) as I don't plan to use RS485.
- for my 4 pulse counters, can I re-use the 4 "one-wire with pull-up" (S1 to S4)?
(I plan to add 1-wire over i2c -- DS2484 to support 1-wire sensors, then I don't need those S1-S4 pins).
Thanks in advance for your support.
