Hi,
I'm wondering whether it's possible to connect one master Rasbery Pi 3 using the GPIO serial pins to many slave Espruino devices through only RX and TX. (only 2 pins)
Looking at the pin diagrams for each the PI is labeled as UART while the Espruino is labeled with USART. Is this a problem?
I've also been reading some articles talking about voltage differences, does anyone have any insight into whether this is possible and what we need to consider?
