SparkFun has introduced a brand new growth board which places a contemporary twist on a basic footprint: the ESP32 Qwiic Professional Mini, powered by an Espressif ESP32-PICO-MINI-N8R2 module.
“This tremendous small IoT [Internet of Things] growth board is a implausible possibility for many who want an embedded system the place house and weight are restricted,” SparkFun’s Chris McCarty claims of the brand new board. “Better of all, using our useful Qwiic system, no soldering is required to attach this Professional Mini to the remainder of your system.”
The board is designed to imitate the scale of the Arduino Professional Mini and compatibles, although quite than utilizing an eight-bit AVR microcontroller it packs an Espressif ESP32 module — giving it a 32-bit dual-core Tensilica Xtensa LX6 processor, 520kB of static RAM (SRAM), 2MB of pseudo-static RAM (PSRAM), 8MB of SPI flash, and an extra 16kB of SRAM within the on-board real-time clock (RTC).
Aimed on the IoT, the brand new board contains single-band IEEE 802.11b/g/n Wi-Fi with information charges as much as 150Mb/s, Bluetooth 4.2 with Bluetooth Low Vitality (BLE), and peripherals together with each analog to digital converter (ADC) and digital to analog converter (DAC), capacitive contact detection, pulse-width modulation, TWAI assist, an Ethernet MAC, and UART, SPI, SDIO, I2C, and I2S buses.
In a ultimate twist on the desk, the board additionally contains Qwiic port for solderless connection to suitable sensor boards and different add-on {hardware} — positioned at a 90-degree angle to the board itself, in order to not spoil the compact footprint with cabling.
The ESP32 Qwiic Professional Mini is now accessible on the SparkFun retailer at $9.95 earlier than quantity pricing; extra data is accessible within the board’s hookup information.
