ESPToy v2

$12.99

ESPToy is a WiFi development board for ESP8266. Version 2.0 has on-board Neopixel color LED, mini buzzer, button, light sensor, LiPo battery jack and charging chip. It has built-in CH340 USB-serial and auto-reset circuit. It’s pre-flashed with a demo software written in Arduino with ESP8266 core.

Note: version 2 is fully compatible with LOLIN Wemos D1 Mini. The auto-reset circuit allows uploading Arduino program directly, without requiring the bootloading procedure as in previous versions. Pins assigned to on-board components are printed at the back of the board.

Description

ESPToy is an all-in-one WiFi development board for ESP8266. This is version 2.0 — it has on-board Neopixel color LED, mini buzzer, button, light sensor, LiPo battery jack and charging chip. It also has built-in CH340 USB-serial and is fully compatible with LOLIN Wemos D1 Mini. The board is pre-flashed with a demo software written in Arduino with ESP8266 core.

New Features in V2.0:

  • Added built-in auto reset circuit, allowing direct upload of a new program (previously requiring a bootloading procedure).
  • Changed color LED to WS2812 Neopixel (previously using standard color LED occupying 3 GPIO pins).
  • Added mini-buzzer to make sound (previously none).
  • Added light sensor and solder jumper (LTJ) to disable or enable the sensor (when enabled, it’s connected to analog pin A0).
  • GPIO pins assigned to built-in components are printed at the back of the board.

* (Version number is printed at the back of the circuit board).

Features:

  • Fully assembled with ESP-12 WiFi module (4MB flash)
  • Demo program written in Arduino with ESP8266 core.
  • On-board color (RGB) LED and push-button.
  • On-board mini buzzer and light sensor (v2 only).
  • On-board micro-USB port and CH340G USB-serial chip (for uploading program and also serial communication).
  • On-board 3.7V LiPo battery jack, charging chip (TP4054) and indicator LED.
  • GPIO pin are mapped out on the side, for connecting external components and breadboard experiments.

Package Includes:

  • One assembled and tested ESPToy circuit board (ESP8266 included)
  • One microUSB cable

Instructions for Demo:

  • ESPToy is pre-flashed with a demo program (source code is available in Github below). First, insert a micro-USB cable to power it up.
  • Wait for a few seconds, a WiFi network with ssid ESPToy-xxxxxx will be created (xxxxxx depends on your specific board). Use your phone or laptop to connect to this WiFi. Then open a browser and type in 192.168.4.1
  • Click any point on the color palette to select a color, the LED on ESPToy will change color accordingly. This makes a simple WiFi-controlled color LED.
  • Hold the button and the webpage will show status change of button (pressed / released).

Using LiPo Battery:

  • ESPToy can be powered by either USB, or an external 3.7V LiPo battery with JST connector. To use battery, plug it into the matching connector on ESPToy.
  • ESPToy has built-in LiPo charging circuit, which allows the battery to be charged from USB cable.
  • An on-board indicator LED shows the charging status: when lit, it indicates the battery is still charging; when off, it indicates the battery is fully charged.

Using Light Sensor (v2 only):

  • Version 2 has added a built-in light sensor. By default, the sensor is disconnected from ESP8266.
  • To enable it, locate the solder jumped marked LTJ close to the upper-left side of the board. Use a soldering iron to connect the jumper — this wires the light sensor signal to analog pin A0.
  • To disable light sensor again (i.e. disconnect it from A0), just remove the solder jumper.
