$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 […]

DeNova Detect natural gas alarm works with Amazon Sidewalk network

Denova Detect Amazon Sidewalk natural gas alarm

New Cosmos’ DeNova Detect is a wireless natural gas alarm that works with the Amazon Sidewalk network designed for low-power, low-bandwidth IoT devices in and around the house, benefiting from free connectivity thanks to the installation base of Amazon devices such as the Echo Show acting as gateways. DeNova Detect does not require wiring to mains, and the device is expected to achieve an extended battery life of seven years, so customers can choose the optimal location for a gas alarm in their homes without needing to be close to an electrical outlet. There’s no need to have an additional gateway such as with LoRaWAN solutions as well as the customer owns one or more Sidewalk-compatible device. Note that Amazon Sidewalk is currently deployed in the US only with global expansion planned for later. Amazon Sidewalk relies on Bluetooth LE inside the home, Sub-GHz GFSK on the sidewalk/around […]
