Pico Wireless Pack adds ESP32 WiFi & Bluetooth module to Raspberry Pi Pico

Pico Wireless Pack for Raspberry Pi Pico

Pimoroni Pico Wireless Pack is an add-on board for Raspberry Pi Pico adding a MicroSD card socket and ESP32 WiFi & Bluetooth module to the popular MCU board. While it’s a nice idea to add wireless connectivity to Raspberry Pi Pico, ESP32 is a dual-core Xtensa LX6 processor clocked at 160 to 240 MHz with WiFi, Bluetooth, and plenty of I/Os that should be able to handle most tasks better than Raspberry Pi RP2040 dual-core Cortex-M0+ processor clocked at 48 MHz by default, although we’ve also seen it overclocked up to 252 MHz. It comes with female headers that allow it to be inserted directly to the back of Raspberry Pi Pico has shown above, or into a “GPIO expander” board like the Pico Omnibus shown below through an SPI interface. Pico Wireless Pack specifications: Wireless module – ESP32-WROOM-32E WiFi 4 & Bluetooth 4.2/5.x module with PCB antenna, 4 MB […]

QMiroPlus-201W – Arm router and Intel NAS in one device with Qualcomm IPQ4019 & Celeron J4125

QNAP QMiroPlus-201W

QNAP QMiroPlus-201W is an unusual networked storage device that’s acting both as a 2.5GbE & WiFI 6 router and NAS combining Qualcomm IPQ4019 Arm SoC for the router functions, and an Intel Celeron J4125 quad-core Gemini Lake processor for the NAS functions. Usually, you’d get the choice of either an Arm or Intel processor, but here QNAP decided to use both to keep the same performance as having separate Arm-based router and Intel-based NAS, but in a much more compact form factor. QNAP QMiroPlus-201W hardware specifications: SoC/memory/internal storage For router SoC – Qualcomm IPQ4019 quad-core Arm Cortex A7 @ 716.8MHz Memory – 512MB DDR3 Internal Storage – 4MB SPI NOR Flash & 4GB eMMC flash For NAS SoC – Intel Celeron J4125 quad-core Gemini Lake processor @2.0 GHz Memory – 4GB DDR4 Internal Storage – 4GB eMMC flash Data Storage – 2x 2.5-inch SATA 3Gb/s (Compatible with 6Gb/s SSD/HDD) bay Networking […]

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

ESP32-WROOM-DA

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 […]
