AirFONTS_1000 is a vector font library accessory board designed and produced by Hezhuo, featuring an SPI interface. It supports reading vector fonts from sizes 16 to 192, as well as the GBK Chinese and ASCII character sets, and supports grayscale display.
When paired with the Air8000 industrial engine series core board, it allows for quick entry into embedded UI development, with example source code already available.

Hardware Wiring Instructions
AirFONTS_1000 connects to the Air8000 core board using six female-to-female DuPont wires.
Note: Be sure to use the accompanying 5CM long DuPont wires for connection. If the wires are too long, it may cause unstable SPI communication.
The Air8000 core board is powered via the Type-C USB port (the power switch on the front of the core board should be set to the power side, and the power consumption test switch on the back of the core board should be set to ON).
In this power supply mode, the VDD_EXT pin provides 3.3V, which can directly power the AirFONT_1000 accessory board.
For demonstration purposes, after powering on the Air8000 core board, it directly provides 3.3V power to the AirFONTS_1000 accessory board through the VBAT pin.
When designing actual projects: generally, a GPIO should be used to control the LDO to power the accessory board, allowing for flexible control of the accessory board’s power supply, thus minimizing the overall power consumption of the project.
