The astronaut desktop TV (Wi-Fi weather clock) is both cute and practical as a desktop ornament, and I have always wanted to make one myself. There are many open-source projects online, but they all require making the board and soldering, which is daunting.
The Beetle ESP32-C3 development board is only 25×20.5cm in size, smaller than a 1.3-inch TFT LCD screen, and comes with a lithium battery charging management chip, making it very suitable for making an astronaut TV.
Hardware Preparation
-
Beetle ESP32-C3 x1
-
1.3-inch or 1.5-inch ST7789 driven TFT screen x1
Introduction to Beetle ESP32-C3
The Beetle ESP32-C3 is a main control board based on the ESP32-C3 RISC-V 32-bit single-core processor chip, designed specifically for IoT (Internet of Things) devices.
The Beetle ESP32-C3 has up to 13 IO ports in a coin-sized volume, so you don’t have to worry about running out of IO ports when making projects. At the same time, the main control board integrates lithium battery charging management functionality, allowing direct connection to a lithium battery without needing external modules, ensuring both compactness and safety of the application.
