ATMegaZero ESP32-S2 board supports OLED displays

EspinalLab ATMegaZero board was introduced last year with Raspberry Pi Zero form factor, the Arduino Leonardo compatible, 16 MHz Microchip ATmega32U4 microcontroller, and a connector for an optional OLED display. The company is now back with an update following the same form factor with ATMegaZero ESP32-S2 board equipped with a more powerful ESP32-S2 single-core processor @ 240 MHz with WiFi connectivity, and most of the same features, including OLED display support, plus a micro USB OTG port and an RGD LED. ATMegaZero ESP32-S2 board specifications: WiSoC – Espressif Systems ESP32-S2 single-core processor @ 240 MHz with WiFi RAM – 8MB PSRAM Storage MicroSD card 256Mbit (32MB) SPI Flash (note: only 16MB can be used for now due to firmware limitations) Display – 32-pin OLED display port compatible with 30-pin SSD1306 and SH1106 based displays Wireless Connectivity – 2.4 GHz WiFi 4 up to 150 MHz with 3D antenna USB – […]

DR8072A embedded router board offers dual 2.5 GbE, WiFi 6 connectivity

We’ve previously found Qualcomm IPQ8072A quad-core Cortex-A53 networking processor in WPQ873 embedded SBC with support for WiFI 6, three GbE ports, one 2.5GbE port, and support for 5G M.2 modems. The design was adapted from Qualcomm HK09 reference design, and now another company, Wallys Communications, has launched another board based on HK09. DR8072A embedded router board is somewhat similar to WPQ873, but does come with two 2.5GbE ports instead of just one, one extra Gigabit Ethernet port, among other smaller changes. DR8072A specifications: SoC – Qualcomm Atheros IPQ8072A quad-core ARM 64 bit A53 @ 2.2GHz part of Qualcomm Networking Pro 600 Platform System Memory – 1x 512MB, DDR4 2,400 MHz 16-bit interface Storage – 256MB NAND flash, 8MB NOR flash Networking and Wireless Connectivity Ethernet 4x Gigabit Ethernet RJ45 ports 2x 2.5 Gbps Ethernet RJ45 ports WiFi On-board 4×4 2.4GHz MU-MIMO OFDMA 802.11b/g/n/ax, up to 1182 Mbps, max 17dBm per […]

AI-Thinker introduces 5 ESP32-C3 modules pin compatible with ESP8266 & ESP32 modules

ESP32-C3 is the first RISC-V wireless SoC from Espressif Systems, and at the time of the initial announcement promised to cost about the same as ESP8266 but adds support for Bluetooth 5.0 LE besides 2.4 GHz WiFi, and retain software compatibility through the ESP-IDF framework. We were also told the goal was to provide ESP8266 compatible modules, and AI-Thinker has just announced five new ESP32-C3 modules compatible with earlier ESP8266 & ESP32 modules as shown in the table below. The table above is quite low resolution but that’s the best I could obtain from the company… It’s also a complete mess, not showing all alternative ESP8266 or mistaken in board sizes. So I’ll try to give a short summary of differentiating features and equivalent ESP8266/ESP32 modules: ESP32-C3F is meant to replace ESP-12F with a 24 x 16 mm form factor. It does add an IPEX connector, besides the PCB antenna. […]
