Authorized North America Distributor Stamp

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:

  • Capacitive touch sensors
  • Hall sensors
  • I2S
  • I2C
  • Ethernet
  • High-speed SPI
  • Low-noise sense amplifiers
  • SD Card interface
  • UART

 

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:

  • Internet of Things (IoT) solutions
  • Sensor networks
  • Voice encoding
  • Wearable electronics
  • Home automation
  • Music streaming
  • MP3 decoding
