Spectra is a JavaScript-based hackable smartwatch based on the ESP32-S3 WiFi and Bluetooth microcontroller that aims to offer the quality of high-end consumer smartwatches with the repairability of a maker-targeted device. The Spectra smartwatch combines the ESP32-S3 microcontroller with a Nordic Semi nRF52832 co-processor to optimize the battery life. The ESP32-S3 is maxed out with 8MB of RAM and 32MB of external flash memory, and the microSD card slot in the watch supports up to a 512GB memory card.

Hackaday ☛ FM Transmitter Remotely Controlled Via ESP32
Imagine you’ve got an FM transmitter located some place. Wouldn’t it be mighty convenient if you could control that transmitter remotely?

CNX Software ☛ KAGA FEI ES4L15BA1 is an ultra-small Bluetooth LE 6.0 and 802.15.4 module based on Nordic nRF54L15 SoC
Japanese company KAGA FEI has recently unveiled the incredibly small ES5L15BA1 Bluetooth LE 6.0 and 802.15.4 module based on Nordic Semi nRF54L15 ultra-low-power Cortex-M33 wireless MCU. We had previously covered the u-Blox NORA-B2 which I already found pretty small at 14.3 x 10.4 x 1.9mm, but the ES5L15BA1 module goes a step further measuring just 8.55 x 3.25 x 1.00 mm with an integrated antenna which could make it the world’s smallest Bluetooth LE module.
