Introduction:
BTT SD/TF Cloud V1.0 is launched by the 3D printing team of ShenZhen BigTree Technology CO.,LTD ., which is a module for wireless file transmission between the master computer and the 3D printer, so that you can get rid of the constraint of plugging SD card.

Module parameters：
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!!
