![]() I changed the lines in my platformio.ini file and used the cu.usbmodemXXXXXXXXXX (actual numbers replaced with XXX). My Mac OS X 11.5.2 Big Sur installation recognized the chip immediately as crw-rw-rw- 1 root wheel 22, 14 Aug 29 08:24 /dev/tty.usbmodemXXXXXXXXXXĬrw-rw-rw- 1 root wheel 22, 15 Aug 29 08:24 /dev/cu.usbmodemXXXXXXXXXX LilyGO also replaced the CP2102 chip with the WCH CH9102 UART chip. But I had to deal with a bigger problem at first. The switched the ESP32-WROVER module with the ESP32 chip, flash and PSRAM are also separately soldered and the module got a “3D antenna”. But when I recently started working for the first time with such a device I ran into big problems.įor the latest version of the LilyGO TTGO T-Camera ESP32 the manufacturer made a couple of significant changes. Lower costs compared to FTDI chips, to the Silicon Labs CP2102 or CP2104. ![]() I assume lower costs and higher availability are the reason for this. Recently more and more ESP32 hardware is appearing with the WCH CH9102 Serial-To-USB chip.
