DFRobot’s Beetle ESP32-C3 Is a Compact RISC-V Dev Board Concentrating on the Web of Issues

DFRobot has introduced the launch of a compact microcontroller board constructed with the Web of Issues (IoT) in thoughts, and utilizing the free and open supply RISC-V instruction set structure: the Beetle ESP32-C3, plus bundled growth board for simpler wiring.

“The ultra-small measurement of Beetle ESP32-C3 would assist customers to beat the dimensions limitation simpler, and now not are subjected to the dimensions limitation of the grasp controller,” says DFRobot’s Eddard Zhu of the brand new board design. “Soldering could be made tough because of the inappropriate energy pin design in lots of controller designs. The extension board has been optimally designed so as to add GDI and extra energy pins for simpler soldering, when connecting Beetle ESP32-C3 to sensors or a display.”

Because the identify implies, the Beetle ESP32-C3 is constructed round Espressif’s ESP32-C3 microcontroller module — that means that it is pushed by a single 32-bit RISC-V processor core working at 160MHz with 400kB of static RAM (SRAM), 384kB of inside flash plus 4MB of exterior flash, and with 8kB of extra SRAM accessible from the on-board real-time clock.

For connectivity, the module — which DFRobot is positioning for the IoT — consists of 802.11b/g/n Wi-Fi connectivity on the two.4GHz spectrum, Bluetooth 5 Low Power (BLE) and Bluetooth Mesh assist, plus 13 digital enter/output pins, six-channel pulse-width modulation (PWM), one SPI bus, one I2C bus, one I2S bus, two UART buses, two every of infrared obtain and transmit channels, two 12-bit analogue to digital converters (ADCs) with as much as six channels, and a DMA controller with three obtain and three transmit channels.

The compact board — with a footprint of simply 25×20.5mm (round 0.98×0.8″) — breaks out its general-purpose enter/output (GPIO) pins to headers at both facet; a bundled breakout board, in the meantime, piggybacks onto the board and affords extra energy and GPIO pins, battery terminals for the on-board lithium-ion administration system, and a ribbon cable connector for an non-compulsory show.

The brand new board bundle is now accessible from the DFRobot website, priced at $7.90 earlier than quantity reductions with assist within the Arduino IDE, Espressif ESP-IDF< MicroPython, C, and Python.
