® TTGO T7 Mini32 V1.5 ESP32-WROVER-E Dual Core PSRAM Wireless Wi-Fi Bluetooth Module Development Circuit Board CH9102
® TTGO T7 Mini32 V1.5 ESP32-WROVER-E Dual Core PSRAM Wireless Wi-Fi Bluetooth Module Development Circuit Board CH9102T7 Mini32 V1.5 Introduce
Note:The difference between T7 V1.4 changed to V1.5:
GPIO has replaced the position, we replaced GPIO16 and GPIO17 two pins that can no longer be used for external expansion with GPIO25 and GPIO27 that can be used with defined functions, so that they can be compatible with those of miniD1 The expansion board is not affected by the original GPIO16 and GPIO17 pins.
