The new SensorTag IoT kit invites you to realize your product idea connected to the cloud.
The new SensorTag now includes 10 low-power MEMS sensors in a small red package.
And it's expandable with DevPacks to make it easy to add your own sensors or actuators.
Connect to the cloud with low-power Bluetooth and Get your sensor data online in 3 minutes.
The SensorTag is ready to go right away with an iOS and Android app, no programming experience to get started.
The new SensorTag is based on The CC2650 Wireless MCU, which offers 75% less power consumption than previous Bluetooth low energy products.
This allows the SensorTag to run on batteries, and offers years of battery life with a single coin cell battery.

The SparkFun ESP32 thing is an upgrade to boards based on the popular ESP8266. What the 32 version has to offer on top? Well one of the largest upgrades is support for Bluetooth communications and nearly 30 I/O pins. Makes it pretty perfect for any IoT solution, right?

This product is a Bluetooth module BLE 4.0 UART without adapter, low energy with serial transceiver.
Logic level conversion circuit. No external level of 5V is needed to become a 3.3V level.
The power input port is protected against the anti-circuit, to avoid the inverted accidental power plug, which leads to the module burn
