ESP8266 four-bit 1588 common anode dot matrix wifi timing clock

1. The 1588 common anode dot matrix is ​​cheaper and has a size of 38x38. The micro port vertical plug can download programs and provide power, while the typec6P vertical plug only provides power.
2. Four-dot matrix integrated board, using ESP8266, the clock RX8025T chip is integrated on the board, and there is no need to use pin headers for connection.

5. Found on March 16 The 8266 package is turned upside down. It needs to be flipped over and soldered again. 6. The PCB modification was completed on March 27. According to the PCB silk screen, the component parameters do not match the schematic diagram. Add the dot matrix pin number on the top layer, and add the ESP12 pin function silk screen on the bottom layer to prevent mistakes.
