1.DIY Kits:

1. PCB motherboard x1. (SMD electronic components on the front and back have been soldered, and the latest version of the firmware has been burned)

2. Several plug-in electronic components and accessories. (User welding is required).

3. 0.96 inch OLED screen x1

2.Assembled board：

The Version is 3.2

You will get the product shown in the picture (without battery)

The latest version of the firmware is shipped by default.The latest firmware version is 3.2.

New in the version 3.2
1.Fixed bug with continuous data transfer to the display.

2.Added a new ability to disable all relays along with the timer display. New cell 35-01 to activate the refunction. Display Off Timer setup - cell 32.You can use this future in your QRP setup where power consumption is critical.

3.Timeout for display reset increased to 2 seconds. This is required for some OLED displays with a very chain on the reset pin.

SWR greater than 1.1 will automatically activate tuning, and the minimum power has been changed from 5W to 1W.

After modification, it can be tuned below 5W.Too low value may result in insufficiently fine tuning (original default is greater than 5W auto tuning), please know that before placing an order.
