$5.5 Banana Pi BPI-PicoW-S3 ESP32-S3 board follows Raspberry Pi Pico W form factor

Banana Pi BPI-PicoW-S3 Raspberry Pi Pico W alternative

Banana Pi’s BPI-PicoW-S3 is a development board following the Raspberry Pi Pico W form factor, but based on Espressif System ESP32-S3 dual-core microcontroller offering both WiFi 4 and Bluetooth LE connectivity. The Raspberry Pi SBCs have inspired many designs, but the Raspberry Pi Pico MCU boards less so. So far, I had only seen the WeAct RP2040 board with the same layout except for a USB Type-C port and a 16MB flash. But the Banana Pi BPI-PicoW-S3 provides a direct alternative to the Raspberry Pi Pico W with a more powerful microcontroller, vector instructions for AI acceleration, BLE, and about the same price at $5.5 plus shipping. Let’s see how the BPI-PicoW-S3 specifications compare to the ones of the Raspberry Pi Pico W in the table below. While the power signal (5V, 3.3V, GND) and GPIO numbers are the same on both boards, there are a few variations here and […]

Orange Pi 800 Keyboard PC – A Raspberry Pi 400 alternative powered by Rockchip RK3399

Raspberry Pi 400 Keyboard PC alternative

There’s now a Raspberry Pi 400 alternative with the Orange Pi 800 Keyboard PC that offers a very similar design, but it is powered by a Rockchip RK3399 hexa-core Cortex-A72/A53 processor. Like the Raspberry Pi model, the Orange Pi 800 comes with 4GB RAM, Gigabit Ethernet, dual-band WiFi 5 and Bluetooth 5.0, two USB 3.0 ports, and one USB 2.0 port, but it also adds 64GB on-board flash storage and features one full-size HDMI port capable of 4Kp60 resolution plus a VGA port, instead of two micro HDMI ports.

UP 4000 x86 SBC review – Part 1: Unboxing and first boot

UP 4000 SBC review

AAEON UP 4000 is a compact Apollo Lake single board computer that’s about the size of a business card or a Raspberry Pi designed for automation, robotics, digital signage, and other space-constrained applications that may benefit from an x86 processor. The company already published some Phoronix benchmarks comparing the UP 4000 SBC against Raspberry Pi 4, NVIDIA Jetson Nano, and the original UP board, but since nothing beats third-party evaluation, AAEON sent a review sample to CNX Software for additional testing. UP 4000 SBC unboxing There are several variants of the board, and I received the UP-APL03X7F-A10-0464 SKU with 4GB RAM, 64GB eMMC flash, and an Intel Atom x7-E3950 quad-core processor. The package includes the board together with a multilingual safety manual that explains you should not immerse the board underwater and should avoid walking on it :). A 12V/5A power supply was also included separately. The power cord was […]
