M5Stamp S3 WiFi and BLE IoT module offers up to 23 GPIOs through 2.54mm and 1.27mm pitch holes

M5Stamp S3, aka M5Stamp ESP32S2 or Stamp S3, is a tiny ESP32-S3 WiFi & Bluetooth LE (BLE) IoT module with a USB Type-C port, over 20 I/Os available through 2.54mm and 1.27mm pitch headers and castellated holes, and a heat-resistant cover. Many of the “new” ESP32-S3 hardware platforms launches these days are often updates from an ESP32 design, and the M5Stack’s M5Stamp S3 is no exception building on the original M5Stamp Pico, and its ESP32-C3 variants, namely M5Stamp C3 and C3U. M5Stamp S3 specifications: WiSoC – Espressif Systems ESP32-S3FN8 dual-core 32-bit Xtensa LX7 microcontroller with AI vector instructions up to 240MHz, RISC-V ULP co-processor, 512KB SRAM, 2.4GHz WiFi 4 (802.11b/g/n), Bluetooth 5.0 BLE + Mesh, 8MB flash as found in the M5Stack ATOMS3 (Lite). Connectivity 2.4 GHz WiFi 4, 20 MHz and 40 MHz bandwidth, IEEE 802.11 b/g/n protocol, up to 150 Mbps Bluetooth 5, Bluetooth Mesh, with supports for […]

Raspberry Pi Pico W gets Bluetooth support in SDK 1.5.0

The Raspberry Pi Pico W board was launched with a WiFi 4 and Bluetooth 5.2 module based on the Infineon CYW43439 wireless chip in June 2022, and I wrote a tutorial showing how to connect to WiFi a few days after the launch, but nothing about Bluetooth. That’s because while the Raspberry Pi Pico W hardware supports Bluetooth, we were told that Bluetooth was not enabled at the time, but might be at a later stage. Alasdair Allan, who is responsible for the Raspberry Pi documentation, said Bluetooth support was scheduled very soon, and the SDK 1.5.0 release of the Pico C SDK is now available with Bluetooth implemented using BTstack low footprint dual-mode Bluetooth stack. Bluetooth support is still considered Beta and the SDK 1.5.0 implements the following key features and updates: New libraries for Bluetooth Low Energy (LE) support. Bluetooth Classic support. Bluetooth Sub Band Coding (SBC) encoder […]

Bluetooth 5.4 adds electronic shelf label (ESL) support

The Bluetooth Special Interest Group (SIG) has just adopted the Bluetooth 5.4 Core Specification with features such as PAwR and EAD designed for Electronic Shelf Label (ESL) systems. The Bluetooth 5.3 Core Specification was adopted in August 2021 with various improvements, and Bluetooth 5.4 now follows with features that appear to be mainly interesting for large-scale Bluetooth networks with support for bi-directional communication with thousands of end nodes from a single access point, as would be the case for Electronic Shelf Label or Shelf Sensor systems. Four new features have been added to Bluetooth 5.4: Periodic Advertising with Responses (PAwR) – PAwR is a new Bluetooth Low Energy (LE) logical transport that provides a way to perform energy-efficient, bi-directional, communication in a large-scale one-to-many topology with up to up to 32,640 devices. Devices can also be allocated to groups allowing them to listen only to their group’s transmissions. An Electronic […]
