ESP32-SOLO-1 is a powerful, generic Wi-Fi+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. Two different temperature variants of ESP32-SOLO-1 are available.
At the core of this module is the ESP32-S0WD chip. ESP32-S0WD is a member of the ESP32 family of chips, which features a single core and contains all the peripherals of its dual-core counterparts. Available in a 5×5 mm QFN, ESP32-S0WD offers great value for money, with its sustained performance when powering complex IoT applications.
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, and 20 dBm output power at the antenna to ensure the widest physical range. Several peripherals facilitate integration with other electronic devices. As such the chip does offer industry-leading specifications and ultra-high 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 developers can upgrade their products even after their release at minimum cost and effort.
