ESP32-WROOM-DA dual PCB antenna WiFi module aims for longer range, better reliability

Espressif Systems ESP32-WROOM-DA is another ESP32 based WiFI & BLE module with a twist as its dual PCB antenna design aims to provides a longer range and more reliable connectivity by automatically switching to a specific PCB antenna depending on signal strength. The new module features ESP32-D0WD-V3 dual-core Xtensa LX6 dual-core processor with a maximum frequency of 240 MHz, along with 520 KB of SRAM and 448 KB of ROM, and has been designed to be pin-to-pin compatible with ESP32-WROOM-32E module found in products such as Pico Wireless, in order to ease migration between the two modules. Espressif did not provide detailed specifications for the new WiFi module, but assuming it’s mostly based on ESP32-WROOM-32E design, ESP32-WROOM-DA should have the following key features & specifications: WiSoC – Espressif Systems ESP32-D0WD-V3 embedded, Xtensa dual-core 32-bit LX6 microprocessor, up to 240 MHz with 448 KB ROM for booting and core functions, 520 […]

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. […]
