Waveshare Launches New SIMCom-Outfitted Espressif ESP32-S3 Boards for Mobile IoT Initiatives

Embedded and hobbyist electronics specialist Waveshare has launched a pair of latest growth boards constructed across the Espressif ESP32-S3 microcontroller and a alternative of SIMCom SIM7670G or A7670E mobile modems — for Web of Issues (IoT) connectivity the place Bluetooth and Wi-Fi aren’t out there.

The ESP32-S3-A7670E-4G is a multi-functional and high-performance microcontroller growth board designed by Waveshare,” the corporate writes of the primary of the 2 units, “[with] built-in A7670E 4G communication module, onboard OV [Omnivision] sequence digital camera interface, TF [SD] Card slot, RGB colourful LED, 18650 battery holder, battery voltage measurement IC, photo voltaic panel charging interface, and different peripherals.”

Equipped in an oblong acrylic housing, the ESP32-S3-A7670E-4 and near-identical ESP32-S3-SIM7670G-4 — delivered to our consideration by CNX Software program — boast very comparable specs. They use an Espressif ESP32-S3R2 system-on-chip with two Tensilica Xtensa LX7 cores working at as much as 240MHz, have 512kB of static RAM (SRAM), 384kB of flash ROM, 2MB of pseudo-static RAM (PSRAM), and 16MB of flash storage. There are built-in single-band 2.4GHz Wi-Fi and Bluetooth Low Vitality (BLE) radios, an on-board Omnivision OV2640 UXGA digital camera, and assist for battery charging by way of USB or photo voltaic inputs.

The place the 2 differ is of their alternative of mobile modem. The ESP32-S3-A7670E-4G makes use of, because the title suggests, the SIMCom A7670E module — offering 4G LTE-FDD and LTE-TDD Cat. 1 and 2G mobile connectivity with voice name assist, together with World Navigation Satellite tv for pc System (GNSS) reception together with GPS. The ESP32-S3-SIM7670G-4G, against this, makes use of the SIMCOM SIM7670G module — which drops 2G and voice name assist and LTE-TDD capabilities, although retains GNSS connectivity whereas including Galileo constellation compatibility.

In each circumstances, the modems can be utilized to offer information connectivity each to tasks working on the ESP32 microcontroller and on exterior units — both offering entry to the modem over USB or utilizing the ESP32 to offer a Wi-Fi hotspot tethered to the mobile connection.

The ESP32-S3-A7670E-4G and ESP32-S3-SIM7670G-4G at the moment are out there to order on the Waveshare retailer for $42.99 and $48.99 respectively, earlier than quantity reductions.
