Beidou module test HT1612

Overview

As required by the course, the Beidou test board was produced. In the actual test, the signal can be found. In the antenna placement window, more than 5

four-layer boards of GPS and Beidou satellites can be found. The impedance matching line width is 32.61mil.

The Beidou module uses USB to ttl to connect to the serial port. The upper level The machine uses ustar, and it has been uploaded to the attachment.

When welding, the inductor package was not adjusted properly, and the pad appeared large, which does not affect the use. The battery package was drawn by myself. If you do not use the battery, you do not need to weld the BAT capacitor. The battery was originally designed for tire pressure battery welding. Use it, forget to design the charging circuit, and temporarily discard

the physical picture (the pins on the left are GND, TXD, RXD, and 5V from top to bottom, and forget to mark them in the picture):

Introduction: A small TV made with a 0.96-inch OLED screen, which can display the time, number of fans of Station B and countdown.

This project is based on a small TV weather clock - you can optimize the PCB layout if you have the skills
. The firmware is from the original author. You can take a look at the original project.
Note: You can directly flash the original author's Bin file, and only the data folder in the uploaded code can display the network configuration web page.
The attachment contains bin and upload tools.
Features:
1. Use Type-C interface.
2. Use ME6211C33M5G-N LDO voltage regulator chip.
3. The charging chip uses TP4059.
4. The main control uses ESP-07S.
5. The display module uses 0.96-inch OLED.

Broadband Amplifier Balanced Mixer
Various CMOS digital functions can be used in many analog fields. For example, a CMOS device (MC74AC00) can be a low-power, low-noise broadband amplifier and a balanced mixer.
