How to prepare microSD card for OpenTX radio

Here, we will introduce how to prepare a microSD card (TF card) for OpenTX radio.

Preparation of microSD card (TF card)

This section describes the procedure for preparing microSD (TF card) card to be set in OpenTX radio. For EdgeTX, see How to prepare microSD card for EdgeTX radio page.
OpenTX/EdgeTX radio uses a microSD card as a data storage area (compatible with SDHC standard). Image / audio data, Lua scripts, backups of radio and drone settings (MODEL information) are saved.
Prepare a blank microSD card. The capacity depends on the amount of icon image and audio data you want to store, but I think 8GB is enough. (RadioMaster's radios only supports up to 8GB, but 16GB could be used.) Format this in FAT32 format on your computer.
MicroSD card (SDXC standard) with a capacity of more than 32GB cannot be formatted in FAT32 using OS standard function. You need to use a free software formatter.
