This is a high quality version of the common T12 soldering controllers. It was designed by me to be compatible with the excellent opensource firmware written by deividAlfa, this purchase includes a $3 donation to the above author. This firmware is not my creation and I want to be fair about this. nonuniform brightness of the display in the picture is from the camera's shutter effect.

I designed this after ordering several T12 stations and never knowing what you would actually receive, even the same hardware version had major variations. Often having counterfeit STM32s, or not even a STM32s when the ad says so, and I had to replace the CPU to run the firmware. Other issues include not being able to use the battery backup as an external RTC was installed and and the battery didn't feed the CPU, I removed the pointless clock function, the firmware has no provision for a clock anyway. Some units also have issues with linear voltage regulators overheating, poor accuracy, NTC being removed from the handle thus not getting good cold junction temperature readings for thermocouple correction, or the controller having an internal NTC and not connecting to the handle's NTC.

The voltage regulation is a switching supply to drop from 24V to 5V and then a linear LDO drops the 5V to 3.3V to eliminate overheating while providing a quite 3.3V for cleaner measurements. High quality components are used. Resistors are over sized in places with higher power dissipation, and are 1% in all measuring circuits. Transistor specs have much more voltage headroom. Jumpers can be configured for the NTC to be in the handle or on the control board. A header and pigtail for a 3V battery(3.3V maximum, 1.5V works in testing) to remember the tip and temperature memory after power down is also included. Requires 24V for operation, approximately 3.5 amps is minimum. Unit will run as low as 12V, but with much slower heat up and less total power. I run one from a 20V cordless tool battery. Firmware has a low voltage cutoff setting to protect the battery.

This listing is for a complete replacement faceplate and control unit for KSGER or Quicko and should mount in the existing enclosure. A 5 pin Ksger handle will plug right in. If you have a Ksger handle without the NTC, there is an option for adding a NTC. You need to see if how many conductors your cable has as you need 5. Option available for 5 conductor 1 meter cable. Or use the NTC internal to the control, select that in the options

Many variations of these controllers exist. You'll have to figure out how yours is setup. Another option is a version(listed separately) without the connector, or preferably get a 5 pin connector for your handle. There are options for the female 5 pin GX12 connector, 5 conductor cable 1 meter long, and a NTC for the handle. Again there are several different setups that you figure out. Or get a handle too.

There is an option for a handle that has the internal NTC. It is the most durable handle with a internal NTC that I have found.

This item is not ROHS compliant. Please contact me with instructions on how to ship to your country if outside of the USA.

Other variations will be coming soon. If you already have a KSGER station with a 6 pin SPI OLED display, I will soon be offering a version of this so you can reuse your existing face plate, display, and GX12-5 connector.
