Story

The project is very variable with many possible modifications.

To begin with, I will describe only the simplest one:

Basic 1 :

- LEDs, two touch buttons, USB power, CR2032 / LIR2032.

BT1 BAT-SMD_CR2032 1

TTP1,TTP2 TTP223-BA6 touch pad detector IC 2

USB1 U-F-M5SS-W-5 MICRO-USB-SMD_MICRO-USB-A9 1

F1 SMD0805 Fuse OR R0805 0R 1

SW1 MSK-12C02-1_5H 1

U1 CH32V003J4M6 SOP-8 1

LED1-LED4 WS2812B-2020 RGB LED 4

CT1,CT2 C0603 0-50pF SEE TTP223-BA6 Datasheet(page 4) 2

C2-C4 C0603 100nF 3

C1 C1206 4.7uF 1

RL1 0603 100R 1

PAD-JUMPER-2- 2

JU1,JQ2 SOLDER SMD-SOLDER

To Program the MCU using USB you need to solder DIO jumper ( pic1).

H1, H2 connectors are designed to connect an external module with another MCU( CH32x033...).

SW1 function:

Vnab- power from USB.

Bat_ch- power from Battery.

Touchpoint:

Right touchpoint -TTP1

Left touchpoint -TTP2

CH32V003J4M6 PINS:

PIN I/O FUNCTION

1 OUTPUT -LED DATA

POWER GND

3 OUTPUT- LED POWER ON/OFF

4 POWER -VDD

INPUT- TOUCHPOINT1

6 INPUT -TOUCHPOINT2

OUTPUT -BATTERY POWER ON/OFF

8 INPUT/ AD -DIO/ FOTORESISTOR
