Opening

To open take a very small screwdrive to pull out the six feets. Don't remove the rubber plates, it won't help.

Flashing

You'll have to connect GPIO0 manually, the switch is connected to GPIO1. It marked the pin in the picture. Because the TYWE2S has 2mm pitch, I made a little adapter to 2,54mm pitch. Then it can easy soldered to the first four pins. From left to right 3,3V, Gnd, Rx, Tx.

Configuration

Configure the USB-Charger as number five, then the next socket as number one and so on. This is the configuration:

• For the other model (Koogeek and AOFO) the GPIO connections are a bit different:
• LED: GPIO1
• Switch: GPIO3
• Socket 1: GPIO5
• Socket 2: GPIO4
• Socket 3: GPIO12
• Socket 4: GPIO13
• USB: GPIO14
