3M Z-Axis Conductive Tape 9703

 3M Z-Axis Conductive Tape 9703 - 2x6 (50mm x 150mm) Strip ID: 1656 - $4.95 : Adafruit Industries, Unique & fun DIY electronics and kits



Z-axis tape is made by 3M, and is used to bond two conductive surfaces together and allow a small (we'd say keep it under 100mA) current to flow through the tape. But here's the cool part: its only conductive across the thickness of the tape itself, not along the length or width. Mindblowing, right? We took a macro shot of the tape above so you can see how it works. Its a regular adhesive tape with little chunks of conductive material every 0.1mm or so. The adhesive does the bonding, the little chunks do the conducting.

And the original ESP8266 source code program can be used to transplant. ESP-M3 module core processor using cost-effective chip ESP8285. The chip integrates the enhanced version of the Tensilica's L106 Diamond 32-bit core processor with on-chip SRAM in a smaller package. ESP8285 has a complete Wi-Fi network function, both can be used independently, can also be used as a slave from other host MCU running. When the ESP8285 hosting application, can be started directly from the external Flash. Built-in cache memory facilitates system performance and optimizes storage systems. In addition, ESP8285 only through the SPI / SDIO interface or I2C / UART port can be used as a Wi-Fi adapter, applied to any microcontr
