MOD-WIFI-ESP8266-DEV

mod_1.png

MOD-WIFI-ESP8266-DEV is a tiny development board that can add WIFI capabilities to existing boards. It uses espressif system’s chip ESP8266EX. All chip signals are exposed for easier access. The board can be soldered to PCB or used with a breadboard. We have provided pads for UEXT and pads for external antenna.ESP8266EX is very highly integrated SoC which includes Tensilica’s L106 32-bit core processor; SRAM; power management unit; RF front end. ESP8266EX has a number of interfaces - I2C, SPI, SDIO and also a number of free GPIO pins. The chip allows the implementation of a WIFI TCP-IP stack with just few extra components beside the ESP8266EX. It’s a very popular IC that attracted a lot of attention upon its launch.

Specifications

  • Main chip: EPS8266EX
  • 2MB (16Mb) SPI flash memory
  • Power LED
  • User-programmable LED
  • Button for easier access to UART boot mode
  • SMT jumpers for different boot modes (FLASH, UART, SDO)
  • PCB antenna
  • UEXT pads for easier access to UART interface
  • Pads for a U.FL antenna connector (if you want to use external antenna)
  • 22 pin holes for easier access to processor pins
  • OSHW design
  • Dimensions: (1.3 x 0.9)” ~ (3.3 x 2.3)cm

The board comes in the form of a DIY kit - if you like soldering this is the OLIMEXINO-85 package suitable for you! OLIMEXINO-85 is a very tiny - (32x20)mm - Arduino-inspired board. It is built around the well-known Little wire design. The same design is also used for the Digispark and Adafruit’s Trinket. The microcontroller comes preprogrammed with “micronucleus tiny85” that is suitable for use with the Digispark’s Arduino distribution.

Specifications

  • DIY design - all components carefully picked for home soldering
  • ATtiny85-PU microcontroller with pre-loaded “micronucleus tiny85” bootloader
  • Tested and working with properly configured Arduino IDE
  • Breadboard compatible via the header
  • Two LEDs - user-programmable and power status
  • Reset button
  • Easy-to-replace components in case of fault
  • Easy-to-solder USB type B connector
  • Open-hardware board, board schematics and layout available for Eagle
  • Open-software board, thanks to the Micronucleus project and the Digispark efforts
  • Dimensions - (1.275 x 0.800)” ~ (32 x 20)mm
