ATU-10 ATU10 QRP by N7DDC Automatic Antenna Tuner 1.4 Version

Now it is 1.4 Version:

New in FW version 1.4

1 - The button glitches solved

2 - More stability in bus transfer to OLED

3 - No continious data transferring to the display

Input power: Minimum 1W, Maximum 15W

The control button has only 3 functions ：

1. a short press resets the tuner and sets all relays to their initial state, in which all reactive elements are disabled and do not affect the signal flow through the tuner,

2. a long press causes the tuner to enter the tuning mode

3. a very long press for more than 5 seconds causes the firmware version to be displayed on the display.

The tuner has 3 power consumption modes:

1. the operating mode, when the display indicates the parameters, lasts 5 minutes,

2. after which the tuner falls asleep and the display turns off. You can wake him up with a short press on the button.

3. After 30 minutes of sleep, the tuner turns off completely and you can turn it on by holding the button for a long time (more than 3 seconds).

The current consumption in the operating mode is 12 mA, in the sleep mode 170 μA, in the off state 37 μA.
