Desktop small clock, electronic mold, GPS speed and altitude meter

Built-in GPS module, intelligent microcontroller control, 8-digit display counter, maximum record is 99999999, theoretically it can be used for 3 years if it is used 24 hours a day at one time per second. If it is used only during the day, it will be 6 Years, if you only knock for 6 hours during the day, it will be 12 years. Using capacitive touch buttons, you don’t have to worry about wear and damage like physical buttons.
The overall size is 39*41.5*38.6, which is small and exquisite and suitable for playing. Built-in 1000ma lithium battery (the internal space can hold two). The stm32f103CBt6 ultra-large storage space chip meets the expansion needs of technical experts. (128K storage space, this project only used less than 30K) high-precision temperature and humidity sensor and independent clock chip.
Low power consumption OLED screen module, can be used as a night light. The theoretical standby time is about a week. The independent power management circuit and voltage acquisition circuit can shut down automatically at low voltage to avoid battery over-discharge. It can switch to display the clock or be used as a GPS speed and altitude measuring tool, or it can be placed in the car and used as a parking sign.
