Lolin S3 Mini – Tiny $5 ESP32-S3 board follows Wemos D1 Mini form factor

LOLIN S3 Mini is a tiny ESP32-S3 WiFi and Bluetooth IoT development board that follows the Wemos D1 Mini form factor and supports its equally tiny stackable shields to add relays, displays, sensors, and so on. Wemos/LOLIN introduced their first ESP32-S3 board last year with the LOLIN S3 board with plenty of I/Os and an affordable $7 price tag. But I prefer the company’s Mini form factor because of its size and the ability to select add-on boards to easily add a range of features to your projects. So I’m pleased to find out the company has now launched the LOLIN S3 Mini following the ESP32-C3 powered LOLIN C3 Mini board unveiled in March 2022. LOLIN S3 Mini specifications: WiSoC – Espressif Systems ESP32-S3FH4R2 CPU – dual-core Tensilica LX7 @ up to 240 MHz with vector instructions for AI acceleration Memory – 512KB RAM, 2MB PSRAM Storage – 4MB QSPI […]

The world’s smallest Bluetooth SoC: InPlay NanoBeacon SoC IN100 in 2.0×1.1mm WLCSP package

world smallest bluetooth soc IN100 WLCSP

InPlay has just announced a Wafer Level Chip Scale Package (WLCSP) for its NanoBeacon SoC IN100, making it the world’s smallest Bluetooth System-on-a-Chip (SoC) at just 2.0 x 1.1 x 0.35mm. The NanoBeacon IN100 is not new per se, and we covered the still tiny Bluetooth SoC when writing about Sparkfun NanoBeacon Bluetooth 5.3 module based on the DFN8 package measuring 2.5×2.5mm. The highlights include its low-code/no-code interface and an ultra-low power consumption of below 1 uW. InPlay NanoBeacon SoC IN100 specifications: Memory – 4 KB SRAM + 4 Kbit OTP memory Bluetooth 5.3 compliant Beacon Modes: Proprietary, BT, Google Eddystone, and Apple iBeacon compliant 2.4GHz RF frequency band, MedRadio band (2.36GHz) Programming-free and firmware-less design Long-range transmission: up to several hundred meters Security Authentication of beacon ID Privacy of advertising payload Supply voltage range – 1.1V ~ 3.6V (Single 1.5V coin battery support) Power consumption Sub-uW power consumption for […]

HealthyPi 5 WiFi & BLE biosignal-acquisition sensor platform captures body temperature, ECG, PPG, SpO₂, and other vitals (Crowdfunding)

HealthyPi 5 is an open-source sensor platform for biosignal acquisition based on Raspberry Pi RP2040 microcontroller and ESP32-C3 WiFi & BLE module used to capture vitals such as electrocardiogram (ECG), respiration, photoplethysmography (PPG), oxygen saturation (SpO₂), and body-temperature data. It is a complete redesign of the HealthyPi v4 Raspberry Pi HAT with many of the same features. While the HealthyPi 5 also follows the Raspberry Pi HAT form factor and can be connected to a Raspberry Pi SBC to analyze the data, it can also be used as a standalone device with the processing handled by the RP2040 dual-core Cortex-M0+ microcontroller and connectivity through an ESP32-C3 wireless module, and data visualized on a 3.5-inch SPI display or a smartphone over WiFi or Bluetooth. HealthyPi 5 specifications: MCU – Raspberry Pi RP2040 dual-core Arm Cortex-M0+ microcontroller @ 133 MHz with 264 KB SRAM Wireless Module – ESP32-C3 RISC-V module with 2.4 […]
