Based on the portable soldering iron open source system IronOS, download the full set of open source materials for Pinecil V1 (software, hardware, etc.)

The portable soldering iron launched by PINE64 in the early days was based on the GD32 design. This time it was upgraded to the second generation product, which was changed to the domestically produced BL706. Its feature is that it supports low-power Bluetooth. The Bluetooth OTA upgrade function will be added to IronOS later. IronOS supports a variety of portable DC, QC, and PD powered soldering irons, and supports all standard functions of smart soldering irons.
