T7 Mini32 V1.5

T7 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.

T7 is the best non-display boatd

It has a very small footprint. It is not breadboard friendly due to double parallel rows of pins. But is is WRover so has PSRAM on the 1.5 version. The 1.3 does not have PSRAM. But for soldered use, it is great, being so small. Dual cores means no delay statements needed. I recommend it as the perfect production board prior to the S3.
