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.

UsbSafe²: an open, programmable dongle for protecting USB devices from USB hosts and chargers

Always stay secure and protect your private data and gadgets when connected via USB. USB connections transfer information and power. UsbSafe² is a device that protects USB-connected hardware from excessive voltage, current, and unauthorized data access. Unfortunately, the practice of “juicing” (accessing data from devices connected to public charging stations) has become very common. UsbSafe² offers a unique combination of anti-juicing mode and fail-power protection. With UsbSafe², you'll feel safer no matter where you are or what you plug in, your valuable gadgets are protected and secured!

Tarocco: Open source closed-loop motor controller for non-small machines (including firmware, PCB, etc.)

Desktop CNC machines often use stepper motors, often because they do not require position feedback sensors, thus reducing system cost. But there are situations where a position feedback sensor is needed or necessary, and the power output of a stepper motor, especially at high speeds, becomes a bottleneck for those who want a better performing machine.
