AT328 + CP2102(firmware update) + control

by Frederic Chang   Last Updated June 27, 2019 06:25 AM

we used the AT328 be a microcontroller to control relays. But we want to use CP2102 to update the firmware, before we used the NANO be a bootloader to update the firmware to AT328.

Is it possible to use one USB port to update the firmware and the control toghter?
