CY7C68013A-56 EZ-USB FX2LP USB 2.0 Develope Board Module Logic Analyzer EEPROM

• 100% brand new and high quality
• CY7C68013A-56 chip: low-power version of the enhanced 51-core, 16KB program data areas, clocked at 48Mhz, 480Mbps high-speed transmission protocol standards, in line with USB2.0 specification, backward compatible with USB1.1.
  
  Firmware, EEPROM: complete the program in-system programming directly with a USB cable to download the firmware, on-board to provide 16K (24LC128) a large program memory (EEPROM), used as storage VID / PID and the USB firmware, the program space to meet the CY7C68013A need.
  
  All GPIO After 2.54mm standard pin lead out, the great convenience learners expand their own design.
  
  With corresponding firmware can be achieved through the core board logic analyzer function.
  
   

MT8870 DTMF Voice Decoder Controller Module with Arduino UNO DUE MEGA2560 sketch

Package ：(Does not include Arduino UNO/MEGA2560): 1 PCS MT8870 DTMF decoder module; 1 PCS Male to Male audio wire (3.5mm jack ) ; Description:  Onboard Complex Frequency Decoder IC MT8870DS DC Power Supply Voltage：4.5V-5.5V(Typical: 5V) Operating Temperature : -40-+85 °C IO Drive : Current Maximum 10mA. PCB Size : 25.4x25.4MM This decoding module is for mobile and fixed telephone voice dialing decoding function Designed specifically for ARDUINO Board.also use for other MCU(AVR PIC MSP430 STM32 ARM7/9/10/11 FPGA/CPLD) Does not require any wiring, can be inserted directly into the UNO/MEGA2560/DUE board to use. 12 Digital outputs decode mobile and fixed telephone keys (0-9, * #).Another 4 Digital output(ABCD) can use "DTMF Dial" Software control.
