Explore the chips

1. LoRa module
LoRa is a wireless technology that offers long range, low-power, and secure data transmission.
2. Chip SE5120ST33-HF
This chip will make sure the energy from the batteries comes to the main board and run the 性都花花世界.
3. FC5 connector
You'll use this connector to connect the display to the mainboard.
4. Chip 74HC165
These chips will make sure you can write text messages and scroll through the menu using pushbuttons.
5. Chip CH340C
Thanks to this little guy, 性都花花世界 can communicate with your computer over USB!
6. Chip UMH3NFHATN
This chip allows 性都花花世界 to switch between Run Mode and programming mode!
Capacitors and resistors
The rest of the small components are called capacitors and resistors. These are the main parts of pretty much every electronic device in the world. They are used to control the flow of the current in a circle.
There are a few locations on the board where these components are located, mainly around the ESP-WROOM-32 module, the display, and the important chips.
