Product introduction:

The ViVi humanoid robot control board is based on the development of our ESP-F WiFi module, which leads to the serial port TTL pin, setting EN and STATE buttons. The product can be built in our humanoid robot firmware to complete the real-time transparent transmission of data from the TTL port to the WiFi/cloud of the device, with low power control and power status indication. This module can directly replace the original wired serial port to realize data transmission and control of embedded devices.


  • Fully compatible with the original wifi transparent transmission module electrical interface and physical interface;
  • The robot firmware is reliable and stable, supports WEB interface configuration download, and graphical action download programming;
  • Based on ESP-F high-performance WiFi module, the overall size: 24mm × 16mm × 3mm;
  • Supply voltage: 4.5V~6.4V, TTL voltage: 3.3V;
  • Lead pin: 3.3V, TXD, RXD, GND;
  • Average current: 80mA; maximum operating current of 3000mA when WiFi data is transmitted;
  • Support serial AT command;
  • Support for reprogrammable, OTA firmware upgrades;
  • Serial port and WiFi data are seamlessly transmitted in real time;
  • Built-in HTTP Web Server, support web page configuration parameters;
  • WiFi supports three modes: AP, STA, and AP+STA.
  • Supports reconnection in WiFi STA mode and reconnection in TCP Client mode;
  • The serial port supports setting the baud rate, data bit, parity, stop bit, and packetization time.
  • Support baud rate (bps): 300/600/1200/2400/4800/9600/19200/38400/57600/74800/115200/230400/460800/921600/1843200/3686400;
  • Operating temperature range: -40 ° C ~ +125 ° C;

CP2102 module tips:

  • TXD: The sender is generally represented as its own sender. Normal communication must be connected to the RXD of another device.
  • RXD: The receiving end is generally represented as its own receiving end, and normal communication must be connected to the TXD of another device.
  • In normal communication, the TXD of its own is always connected to the RXD of the device!
  • Self-receiving: RXD is connected to the TXD of other devices during normal communication. Therefore, if you want to receive the data sent by yourself as the name implies, that is, you receive the data sent by yourself, that is, its own TXD is directly connected to RXD, which is used to test its own transmission and reception. Whether it is normal or not is a quick and simple test method. When a problem occurs, the test is first performed to determine whether the product is faulty. Also known as loopback testing.
  • Level logic:
  1. TTL level: Normal data indicates binary, +5V is equivalent to logic "1", 0V is equivalent to logic "0", called TTL signal system, is positive logic
  2. RS232 level: -12V to -3V, equivalent to logic "0", +3V to +12V logic level, equivalent to logic "1", is negative logic

CP2102 module product description:

  • The main chip is CP2102, and the virtual serial port is generated after the driver is installed.
  • USB power-up, the output interface includes 3.3V (<40mA), 5V, GND, TX, RX, the signal pin level is 3.3V, positive logic
  • On-board status indicator, transceiver indicator, the status indicator will be on after the driver is properly installed. The transceiver indicator will flash during communication. The higher the baud rate, the lower the brightness.
  • Support baud rate from 300bps to 1Mbps
  • Communication format support: 1) 5, 6, 7, 8 data bits; 2) support 1, 1.5, 2 stop bits; 3) odd, even, mark, space, none check
  • Support operating system: windows vista/xp/server 2003/200, Mac OS-X/OS-9, Linux
  • USB head is male, can be directly connected to the computer USB port
