The Espressif ESP-SOLO-1 is a high-performance module built around the ESP32-S0WD chip and capable of supporting Wi-Fi, Bluetooth (BT), and Bluetooth Low Energy (BLE).
This combination module comes standard with 4MB flash memory and offers a single-core 160 MHz processor with all the great features and peripherals of a dual-core system.
Peripherals included in the ESP-SOLO-1:
The integrated ESP32 chip delivers a sleep current less than 5 µA, making the module essential for battery powered Internet of Things (IoT) applications. With a data rate, up to 150 Mbps and output of 20 dBm the device is able to support a wide range of uses.
The ESP-SOLO operates on freeRTOS LwIP, and TLS 1.2 with hardware acceleration built-in. It is fully-customizable with an open-source platform and secure encrypted over-the-air (OTA) updates, that allow firmware to be updated in deployed products with low cost.
GitHub provides a large collection of example code and information for device customizations.
Common applications include:
