Magic button v1.1 version

There have been no updates since version 1.0 was released.

I always feel a bit regretful and there is still a lot of room for improvement.

It's time to release version 1.1. It's easier to solder. They are all single-sided components and are limited to personal play.

The code needs to modify the pin definition based on 1.0

Overview:

1. Materials use 3D printing + acrylic
2. The shell of the button retains the original design and adds an acrylic + frame structure.
3. PCB circuit + mechanical structure redesigned, the structure has stabilized
4. Optimize power consumption standby
5. Add expansion pins to facilitate adding external sensor modules
6. The battery is 402025, about 150mAh

8. 4 countersunk head screws M1.0x8, 4 hex nuts M1.0, M1.2 are also supported.
9. OLED supports two types of screens on the market, 28P (ssd1315) and 16P welding (ssd1306)
10. Add 6-axis sensor to increase compatibility and facilitate purchase

Production:

PCB

Composed of 3 PCBs 0.8mm thick:

1. btn
2. display_xxxx
3. mcu_xxxxx

The ones in the preferred box are basically the same as version 1.0

3D printed structural parts

Four structural parts need to be printed. It is recommended to use light-curing printing. You can place an order at 3D Monkey:

1. Bottom cover (choose material, such as white resin, which can transmit light)
2. Pressure plate
3. Overall shell
4. Acrylic shell (panel printing needs to be done separately in Lichuang Mall)
5. Transparent shell ( choose one of 4 and 5 )

panel

If you choose item 4 in 3D printing, you need to print the panel

Requirements are as follows:

1. Acrylic
2. 1.5mm thick
3. Adhesive
4. Transparent (black translucent optional)

Accessories

Screw: M1.0 or M1.2 countersunk head, depth 6-8mm

Nut: M1.0 or M1.2, hexagonal nut

software

Notice:

If you are using the nrf52 version of PCB, you need a JLINK downloader (supports SWD) to download the code.
