• Supporting Lua program, easily to develop • Supporting three modes: AP, STA, and AP+STA • Strong function with support LWIP protocol, Freertos • Small volume, easily embedded to other products The development board breaks out all the module’s pins to 0.1″ headers and gives a CP2102 USB-TTL sequential connector, programming and reset catches, and a power controller to supply the ESP32 with a stable 3.3 V. Espressif multiplied down on the CPU assets for the ESP32 with a double center, running at 160MHz and tons more sticks and peripherals. The client may likewise control off the CPU and utilize the low-control coprocessor to always screen the peripherals for changes or intersection of limits. ESP32 coordinates a rich arrangement of peripherals, running from capacitive touch sensors, Hall Website https://circuit.pk/product/199

Working principle of optical imaging touch whiteboard Working together, two or four optical sensors track the movement of any object close to the surface by detecting the interruption of an infra-red light source. The light is emitted in a plane across the surface of the screen and can be either active (infra-red LED) or passive (special reflective surfaces). At the heart of the system is a printed circuit controller board that receives signals from the optical sensors. Its software then compensates for optical distortions and triangulates the position of the touching object with extreme accuracy. By using optical sensors at two corners of the screen, Optical Touch “sees” the touching object from two angles. The result is a high degree of accuracy, with no contact pressure required. No special coatings and films are needed—there is nothing to scratch, wear out, or cloud the display image. The screen can be sealed against dirt, dust, moisture, ideal for heavily used kiosks in public areas Why do you choose our company? Company principle: Honesty Oriented, Customer Foremost Product line: First-class technical workers, professional skills, diligent working spirit and good working environment that make sure the products in high quality and continuously capacity.

Breakout - MPR121 SparkFun Description: This is a breakout board for Freescale’s MPR121QR2. The MPR121 is a capacitive touch sensor controller driven by an I2C interface. The chip can control up to twelve individual electrodes, as well as a simulated thirteenth electrode. The MPR121 also features eight LED driving pins. When these pins are not configured as electrodes, they may be used to drive LEDs. There a four jumpers on the bottom of the board, all of which are set (closed) by default. An address jumper ties the ADD pin to ground, meaning the default I2C address of the chip will be 0x5A. If you need to change the address of the chip (by shorting ADD to a different pin), Capacitive Touch Sensor make sure you open the jumper first. Jumpers also connect SDA, SCL and the interrupt pin to 10k pull-up resistors. If you don’t require the pull-up resistors you can open the jumpers by cutting the trace connecting them.
