AIR401/LT5805A Development Board

Overview

The Hezhou Air401 development board, as confirmed by customer service, is no longer in use. The good news is that the so-called Air401 is actually an LT5805A, a combined LT8960L and PY32F002B chip. Check out the Taobao store "Juxin Integrated Circuits" for an SDK; it supports 2.4GHz communication and Bluetooth broadcasting, and costs less than 1 RMB. Specific parameters are as follows:

Development board size: 2.64 * 3.12 CM, very small. It has an onboard SHT30 temperature and humidity sensor (optional), with all pins exposed.

The Type-C port is only for power supply and is not essential. The Air401 only supports SWD programming and does not support serial communication. Please prepare a DPlink or other SWD-compatible link. Programming can be done using PyOCD: `
pyocd flash -t PY32F002Bx5 -f 100kHz ./Air401.hex`
