F103_UNIT_Rework

This is a two-channels combined soldering iron rework station for Hakko T12, JBC C245 and 858D Hot Air Gun based on STM32 micro controller. The soldering controller uses ili9341 TFT display with SPI interface without touch-screen. There are several display variants (2.2", 2.4", 2.8" or 3.2") in the market, so you can chose any of them that satisfies your requirements. Yet, you can use the IPS display based on ili9341v IC. The controller in main photo equipped with the 2.8" TFT display.

The soldering controller can manage any type of soldering iron (JBC or T12) and Hot Air Gun at the same time. In the main mode, you can activate the iron or Hot Air Gun or activate them simultaneously. The information about two devices is displayed on the main screen and each device is managed by a dedicated rotary encoder. There are two GX16-6 connectors in the controller that can be used to connect the soldering iron: in the front pannel and in the rear pannel. The read connector can be used to manage the JBC C245 tips and the front connector can be used to manage both types of iron, Hakko T12 or JBC. It is convenient to connect the JBC base stand to the rear connector and when you use the JBC iron without a base stand it can be connected to the front socket. You cannot connect the Hakko T12 and JBC irons to the front and rear connectors simultaneously, because the controller can manage only simgle soldering iron at a time.

To simplify managing devices two rotary encoders are used in the controller. The upper encoder manages the JBC or T12 soldering iron and the lower encoder deditated to the Hot Air Gun excusivelly. Also, the main menu is available through long-press the lower encoder.

The automatic mode switch that turn the Hot Air Gun off is still optional and can be placed on the rear panel, like mine. To simplify using JBC iron, you can buy the dedicated JBC base stand or implement optional push button to simulate JBC tip change and optional switch to simulate JBC on-hook feature when the JBC iron is not connected to the controller. Both optional switches and be placed near the JBC socket on the rear side of the controller.
