FAQ
- Can external power supply be used together with USBTTLC to supply power to the system？
- Because the 3.3 power current of the current version of USBTTLC is too small（within 100ma）, it is not recommended. In test phase, you can only use USBTTL, and after the completion of the program debugging, you can use external power supply directly to supply power.
