• Wide operating temperature range. Tested -20 +40 Celsius
• Temperature and humidity sensor Si7021
• High Accuracy Temperature Sensor ±0.4 °C (max), –10 to 85 °C
• Precision Relative Humidity Sensor ± 3% RH (max), 0–80% RH
• Authentication security - Atmel ATSHA204A Crypto Authentication Chip
• Dualoptiboot bootloader. Implements over the air (OTA) firmware update ability
• FTDI header for programming
• Reverse polarity protection.
• Arduino pins A0 A1 have pads on PCB for any special needs.
• Magnet sensor triggers hardware interrupt 1

Comes with Arduino example sketch door.ino. It uses MySensors API.

Overview

If you are familiar with Arduino boards, the Switch Box is Arduino pro Mini with onboard HopeRF RFM69-CW radio and crypto authentication chip. To save some board dimensions the Switch Box does not have onboard USB-Serial converter. You need to buy FTDI Adapter for programming. HopeRF LoRa RFM95 or RFM69 433/868/915 MHz provides extremely good range. Onboard Atmel ATSHA204A CryptoAuthentication chip secures communication with other controllers. Some IOT ideas based on the Switch Box and similar controllers plus complete specs you may find here my GitHub page

Pin out: Please check documentation link. Note the link is for PIR sensor as the door\window sensor shares same board without PIR sensor soldered.
