Kode Dot – An easy-to-use, pocket-sized, battery-powered ESP32-S3 devkit (Crowdfunding)

Kode Dot is a pocket-sized ESP32-S3 maker device for prototyping with a built-in 2.13-inch AMOLED, a 500mAh battery, a 9-axis IMU, a microphone and a speaker, an RTC, a few buttons, a GPIO header, and a magnetic connector for expansion. Kode Dot is designed to simplify the prototyping process. Users can still write code using the Arduino IDE, PlatformIO, or ESP-IDF framework and upload it via the kit’s USB-C port, but thanks to kodeOS firmware, each program becomes a standalone app with its own name, icon, and interface, accessible from the graphical user interface. Kode Dot specifications: SoC – Espressif Systems ESP32-S3 dual-core microcontroller with 2.4 GHz Wi-Fi, Bluetooth 5 LE, ESP-NOW peer-to-peer protocol System Memory – 8 MB octal PSRAM Storage 32 MB octal SPI flash microSD card slot Display – 2.13-inch Color AMOLED with 502 x 410 resolution Audio ICS-43434 MEMS microphone 1W MAX98357A speaker amp USB – […]

Giveaway Week 2025 – RAKwireless Blues.ONE LoRaWAN, LTE-M, and NB-IoT devkit

It turns out we don’t have two, but three companies offering free samples on CNX Software this year. The last one is a regular, and RAKwireless joins us for the fifth year running with a Blues.ONE LoRaWAN, LTE-M, and NB-IoT devkit that can be useful for industrial automation and asset-tracking applications. Regular readers may recall that it is the same prize as last year. While I usually prefer getting a new devkit, the company didn’t launch any this year (just some Meshtastic kits). The good news is that if you missed out last time around, you have a chance to give it another go. Here’s what the winner will get as a reminder: RAK4631 WisBlock Core Module based on Nordic Semi nRF52840 Arm Cortex-M4F microcontroller @ 64 MHz with 1 MB Flash, 256 KB RAM, Bluetooth Low Energy 5.0 protocol stack Semtech SX1262 LoRa Transceiver with LoRaWAN 1.0.2 protocol stack […]
