1) The module adopts ESP-12S, which is based on ESP8266's low-power UART-WIFI chip module;

2) The main frequency supports 80MHz and 160MHz;

3) Spectrum range: 2412-2484MHZ;

4) Logic voltage: DC 3.3v;

5) USB input voltage: DC 5V;

6) Size: SD-24mm *58.3mm; TF - 24 mm * 45.5 mm;

7) Transmission file name format requirements: only support the file name consisting of ASCII code;

8) TF card memory: 128M.

Scope of application:

Any SD card interface that communicates via SPI can be plugged in and used directly.

Such as: BIGTREETECH SKR series motherboard、GTR  motherboard、BIGTREETECH TFT24 V1.1、BIGTREETECH TFT35 V3.0、BIGTREETECH TFT35-E3 V3.0 and so on.

Note: All SD card interfaces that communicate via SDIO mode cannot be used. For example: BIGTREETECH TFT35 V2.0.
