M5Stack Core2 is a neatly packed ESP32 IoT development kit with a 2-inch touchscreen display, motion sensor, a microphone., and a built-in battery that was launched last September. The hardware has been selected by Amazon Web Services and gone through some small modifications including the addition of a secure element, and a yellow paint job giving birth the the “AWS IoT EduKit” hardware and software solution designed to “learn how to build IoT applications using AWS services through a prescriptive learning program”. M5Stack Core2 for AWS IoT EduKit specifications are pretty similar, but with a few tweaks here and there: SoC – Espressif ESP32-D0WDQ6-V3 dual-core Xtensa LX6 processor clocked at up to 240MHz with 520KB SRAM, Wi-Fi, and dual-mode Bluetooth connectivity External Memory – 8MB PSRAM Storage – 16MB flash storage, MicroSD card slot up to 16GB Display – 2-inch IPS LCD screen with 320×240 resolution (ILI9342C driver), and touchscreen support (via FT6336U controller) Audio – Built-in 1W speaker, SPM1423 […]
Arm Cortex-M33 core with Arm Trustzone security was first unveiled in 2016, and since then several silicon vendors introduced secure Cortex-M33 microcontrollers with, for instance, Nordic nRF91 LTE-IoT SoC, STMicro STM32L5 MCU family, or NXP LPC551x/S1x. Renesas has now added one more alternative with RA6M4 Cortex-M33 microcontroller family clocked at up to 200 MHz with increased performance and security compared to their earlier Cortex-M4 RA6 microcontrollers clocked at 120 Mhz.

Bluetooth 5.0 has two main new features: high speed (2Mbps) and long-range. But as we’ve seen in our nRF52840 vs nRF52832 vs nRF52810 comparison is that only nRF52840 supports Bluetooth 5.x long range. Bluetooth 5 long range is achieved with two new lower bit rates of 500 kbps and 125 kbps. So what do you do if you’d like a longer range and keep using the higher bit rates? You add a power amplifier and LNA to your board, and that’s exactly what Nikolaj (RFCat) did with RFCat N32 board based on Nordic Semi nRF52832 wireless SoC. RFCat N32 board specifications: Wireless module – Meshtek-H52 Smart Mesh Module with integrated PCB antenna based on Nordic Semi nRF52832 Arm Cortex-M4F Bluetooth 5-ready SoC (See datasheet) Skyworks RFX2401C PA &LNA with 18.9dBm TX gain and 11dBm RX gain USB – 1x USB-C port for power, programming and debugging via CP2102N USB to UART bridge I/Os – 2x 13-pin 2.54mm pitch headers with […]
