SENSE D01 BOARD is an embedded Board with a form factor of just 86.36 × 40 mm based on a module of Espressif ESP32-WROVER.

ESP32-WROVER is a powerful, generic WiFi-BT-BLE MCU module that targets a wide variety of applications, ranging from low-power sensor networks to the most demanding tasks, such as voice encoding, music streaming and MP3 decoding. This module is provided in two versions: one with a PCB antenna, the other with an IPEX antenna. ESP32-WROVER features a 4 MB external SPI flash and an additional 8 MB SPI Pseudo static RAM (PSRAM).

The core of this module is the ESP32-D0WDQ6 chip. The chip embedded is designed to be scalable and adaptive. There are two CPU cores that can be individually controlled, and the CPU clock frequency is adjustable from 80 MHz to 240 MHz. The user may also power off the CPU and make use of the low-power co-processor to constantly monitor the peripherals for changes or crossing of thresholds.

ESP32 integrates a rich set of peripherals, ranging from capacitive touch sensors, Hall sensors, SD card interface, Ethernet, high-speed SPI, UART, I²S and I²C. The integration of Bluetooth, Bluetooth LE and Wi-Fi ensures that a wide range of applications can be targeted, and that the module is all-around: using Wi-Fi allows a large physical range and direct connection to the Internet through a Wi-Fi router, while using Bluetooth allows the user to conveniently connect to the phone or broadcast low energy beacons for its detection. The sleep current of the ESP32 chip is less than 5 µA, making it suitable for battery powered and wearable electronics applications. The module supports a data rate of up to 150 Mbps, 802.11b at 13.5 dBm and 802.11g,n at 18.5 dBm of output power at the antenna to ensure the widest physical range.

As such the module does offer industry-leading specifications and the best performance for electronic integration, range, power consumption, and connectivity. The operating system chosen for ESP32 is FreeRTOS with LwIP; TLS 1.2 with hardware acceleration is built in as well. Secure (encrypted) over the air (OTA) upgrade is also supported, so that users can upgrade their products even after their release, at minimum cost and effort.

This embedded module supports these peripherals: SD Card, CAN Bus, UART, ADC and DAC, 3 LEDs and 8 GPIO. This board is suitable both for IoT applications, due to its rich connectivity, and for industrial applications, since it can accept supply voltages in the range +9...+36 VDC (absolute voltage range). Please refer to following chapter for a complete list of all peripherals integrated and characteristics.
