The SparkFun ESP8266 WiFi Shield is an Arduino compatible shield for the ESP8266 WiFi SoC – a leading platform for Internet of Things (IoT) or WiFi-related projects. There are a variety of designs based around the ESP8266, including tiny, modular boards and more accessible development boards like our very own SparkFun ESP8266 Thing.
This module uses the newest 2.4GHz transceiver from Nordic Semiconductor, the nRF24L01+. This transceiver IC operates in the 2.4GHz band and has many new features! Take all the coolness of the nRF2401A and add some extra pipelines, buffers, and an auto-retransmit feature - very nice!
The SparkFun MP3 Player Shield is an awesome MP3 decoder with the capabilities of storing music files onto a run-of-the-mill microSD card, thus giving you the ability toadd music or sound effects to any project. With this board you can pull MP3 files from an microSD card and play them using only one shield.
The Nextion Enhanced versions are more powerful than the standard ones. Compare to the basic Nextion displays, the enhanced ones have added some new functions, such as: supporting built-in RTC, supporting save data to Flash, supporting GPIO, larger flash capacity and larger CPU clock.
Duo is a thumb-size development board made to simplify the building process of Internet of Things (IoT) products. Everything you need is built into the Duo. It contains WiFi, BLE and Cloud, all in a compact form factor that makes it ideal for your first prototype, a finished product, and everything in between.
The Arduino Uno Wi-Fi is the new Arduino Uno with an integrated Wi-Fi module! The board is based on the ATmega328P (datasheet) with an ESP8266 Wi-Fi Module integrated (datasheet). It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz ceramic resonator.
