Hi,
I'm interested in purchasing a few of your PCA9615 boards for an ongoing project.
However, I cannot see how to disable the termination resistors on your board? Is it going to be a case of removing the 6 resistors on all boards except the termination one?
I have 24 BME280 boards that i'd like to connect to an ESP32. They are spaced out 50cm over 4 metres X 3 levels with the ESP32 in the centre.
BME280 ------ BME280 ------ BME280 ------ BME280 ------ BME280 ------ BME280 ------ BME280 ------ BME280
BME280 ------ BME280 ------ BME280 ------ BME280 ESP32 BME280 ------ BME280 ------ BME280 ------ BME280
BME280 ------ BME280 ------ BME280 ------ BME280 ------ BME280 ------ BME280 ------ BME280 ------ BME280
(Total length is 4 metres, height is 1 metre. Longest run will be 2.5 metres)
Thanks
