  1. The side with word is the radiating surface(code side) The other side with no word is the Endothermic surface(hot side) Learn More
  2. The Wireless Charging Module can be applied in electronic equipments in common use for close wireless charging or power supply. Consisted of a transmitter and insolation coil, it could serve as a replacement for the Wireless Power Supply with stable 12V output voltage and maximum 600mA output current. Its small size and insolation coil are more suitable for using in wireless project. Learn More
  3. TDA7297 amplifier board, with the terminal, 2.0 dual-channel 15W +15 W, 4-8 European 10-50W speaker can be connected, a large volume of small stature, a wide range of applications. Learn More
  4. 4 Frequency GPRS/GSM Module-EFCom Pro is an ultra compact and reliable wireless module. It is a breakout board and minimum system of SIM900 Quad-band GSM/GPRS module. It can communicate with controllers via AT commands (GSM 07.07 ,07.05 and SIMCOM enhanced AT Commands). This module support software power on and reset. 
    EFCom Pro is base on SIM900 4 Frequency GPRS module

    The GPRS is configured and controlled via its UART using simple AT commands. Just connect on the Arduino/AVR/ARM/FPGA/CPLD board, you could easily use AT command to control it. EFCom Por can be connected to PC via FT233RL, recommend our FT232 Bee adapter

  5. The Color sensor module based on TCS3200, which is a programmable color light-to-frequency converter, it could filter RGB data from source light and convert it to a square wave(50% duty cycle) with frequency directly proportional to light intensity (irradiance). The full-scale output frequency can be scaled by one of three preset values via two control input pins(SO, S1 Selectable Options 2%, 20%, 100% frequency),and pin S2, S3 to control the filter of RGB. Digital inputs and digital output allow interface to a microcontroller or other logic circuitry directly. Output enable (OE) places the output in the high-impedance state for multiple-unit sharing of a microcontroller input line. At last, user can calculate the color of the light by RGB values.
