I am a programmer who is trying his best to access stackoverflow by any means anyway. Currently I am working on open source hardware (micro and stupid "smart" things) as well as simple cloud platform to delivery local turnkey solutions to selected industries.

Thanks to Stackoverflow QA services, I can get helps from many experts and gurus.

My designs:

• Tools like CMSIS-DAP debugger and pitch converter
• Iot boards like STM32F407/KL25Z/LPC1114/STM32F103
• Iot connectivities like 2G/3G M2M/ WiFi/BLE/6LowPAN/Sub-1GHz
• E-Paper QRCode device (E-Badge)
• Patented RFID classified wallet
• High IO, long pull IOT web
