; ----------------------------------------------------- YD-ESP32-S3 N16R8 ----
; Detected on this machine: ESP32-S3 (QFN56) rev v0.2, 16MB quad flash,
; 8MB octal PSRAM, MAC 24:58:7c:cd:9a:d8, CH343 bridge (1a86:55d3).
;
; The board has two USB-C sockets. This env assumes the one marked COM (the
; CH343 UART bridge). Serial is therefore real UART0, not USB CDC, which also
; sidesteps the CDC-blocking behaviour that bit us on the C6.
