Discussion - Hardware / FT230XS
« on: January 05, 2021, 02:26:48 PM »
Hi Gents,
I had/have an issue where our FT230XS is supplying current into our MCU over the FT230XS's TX and RX lines. And keeping the MCU a bit alive across reboots. Some current limiting resistors seem to be needed on these two lines. But I'm curious if this is a common issue / known limitation. Are series resistors the suggested design? And what is going on with the FT230XS whereby it can supply current on TX/RX?
