【Overview】

[] The physical object of the Air103 chip is only 6mm x 6mm, packaged in QFN56, and 44 sets of GPIO are available. The chip integrates a 32-bit processor, with built-in 1M bytes of Flash and 288K bytes of RAM, with a maximum main frequency of 240MHz; Supports numerous screens, including monochrome I2C screens, multiple color SPI screens, and multiple monochrome ink screens.

[] All pins are exported from the Air103 development board, and the onboard Type-C can download code without the need for a downloader, making it easy to use and more flexible in applications. LuatOS official adaptation, script development does not require a complex development environment, and comes with rich use cases and tutorials to quickly get started.
