If you're using the Shim for the Espruino Pico you needn't worry about this - just solder the Shim to the Espruino and the ESP8266. To add a voltage regulator (needed on the original Espruino board), we'd suggest you wire up an LD1117AV33 as follows: However some versions use 115200 baud - see below. The board communicates at 9600 8 baud, 1 stop bit, no parity. As the board has its own voltage regulator, you'll need to run it off of 5V, not 3.3V. libraries for Arduino/CircuitPython/Raspberry Pi Python, schematics. If you're using the Adafruit HUZZAH board, you'll only need power, GND, and RX/TX for it to work. megaTin圜ore which brings Arduino peripheral support to this series of chips. If you're not using the ESP8266 shim, you will almost certainly need to add at least a 10uF capacitor between GND and the ESP8266's 3.3v line to get it to work reliably. You'll need an extra 3.3v regulator when using this on an original Espruino board as it can't supply enough power. Shim Version 2īoot mode - must be 3.3v to enable WiFi, 0v for bootloader more.ĬHip Power Down, 3.3v to enable WiFi, 0v for off. Johnny-Five transmits basic I/O instructions to the connected board via a USB serial, which acts as a thin. For the majority of the supported platforms, JavaScript is executed on a host machine that runs Node.js. If you have the v1 shim and your Pico has pins pre-installed, you will need to cut the black plastic away from the last 3 pins in order to fit the shim. While it is a great library for programming using Arduino or other popular microcontrollers, it lacks one basic feature, portability. Please see the videos below for more information on wiring the shims up: Shim Version 1 A 47uF, 6.3v 1210 MLCC capacitor like this one is perfect. It's often a good idea to fit the capacitor if you're planning on powering anything else from the Pico's 3.3v rail. There are pads for an optional 3.3v regulator (not needed) and a 1206 or 1210-style capacitor. The Shim available for the Espruino Pico helps to adapt the ESP8266 to fit onto the Pico, while still keeping all of the IOs intact. Have at least 1MB, but if you have an ESP01 board with a blue PCB, that likely means Note: ESP8266 boards come with differing amounts of flash memory. Support is provided in Espruino by the ESP8266WiFi ( About Modules) and ESP8266WiFi_0v25 ( About Modules) modules.ĭifferent versions of the ESP8266 firmware communicate at different baud rates and have subtly different commands - make sure you use the ESP8266 module that corresponds to the ESP8266 firmware version that you have. It has an ESP8266, plus a separate processor for Espruino with loads of RAM and CPU power. If you want to run theĮspruino Firmware directly on an ESP8266 board, see this page insteadĭo you want a board that already has WiFi? Check out Espruino WiFi. Note: This page contains information on using an ESP8266 module with an Espruino board.
