At the core of this module is the ESP32-S0WD chip, which is a member of the ESP32 series of chips. ESP32-S0WD has a single core, although it is still capable of getting connected to all the peripherals of its dual-core counterparts. ESP32-S0WD offers great value for money, having a highly stable performance in various complex IoT applications.

ESP32-S0WD Specifications

  • SoC: ESP32 with a single-core, low-power Xtensa 32-bit LX6 microprocessor
  • 448 KB of ROM for booting and core functions
  • 520 KB of on-chip SRAM for data and instructions
  • 16 KB of SRAM in RTC
  • QSPI flash/SRAM up to 4 × 16 MB
  • Power supply: 2.3 V to 3.6 V
  • Temperature sensor, touch sensor, ADC, DA
  • Connectivity: Bluetooth (Classic & Low-Energy) and  Wi-Fi b/g/n dual mode

The combination of Wi-Fi with Classic and Low Energy Bluetooth ensures unparalleled connectivity in different application scenarios. Wi-Fi enables internet connectivity over a large area, while Classic Bluetooth allows users to securely connect ESP32-SOLO-1 to their mobile phones for exchanging data over short distances by using short-wavelength UHF radio waves. Additionally, ESP32-SOLO-1 can function as a beacon, broadcasting its identifier via Bluetooth Low Energy to portable electronic devices within a maximum radius of 50 meters.

The sleep current of the core chip in ESP32-SOLO-1 is less than 5 μA, which makes the module suitable for battery-powered applications and wearable electronics. The module supports data transfer at 150 Mbps, while having an output power of 20.5 dBm at the antenna. Several peripherals facilitate integration with other electronic devices, thus offering industry-leading specifications and great performance.
