RS232 Module 13.2 with DB9 Male Connector _RPI_POWER_HAT the TFT feather uses about

the TFT feather uses about 100uA of current

and a power regulator to supply the ESP32 with a stable 3

Works with any Raspberry Pi from ZERO to 5

As the camera requires a separate power supply from your GPIO pins (using the included cable)

RS232 Module 13.2 with DB9 Male Connector _RPI_POWER_HAT the TFT feather uses aboutThe RS232M Module 13. 2 is an expansion module of RS232 serial communication with isolation, using the scheme of TD301D232H serial port conversion chip and male DB9 interface to enable the interface conversion between RS232 and TTL CMOS logic level signals, and using the F0505S 2WR3 DC DC power module to enable electrical and noise isolation functions, toggle switch and coding switch. It enables the pass through or cross switching of DB9 signal lines,
