NXP i.MX 8M Mini Pico-ITX SBC Comes with Audio DSP, Optional PoE and Google Coral M.2 Module

EMB-2237-AI SBC PoE

We’ve covered several NXP i.MX 8M Mini SBC‘s since the announcement of the processor in 2018 as the first i.MX SoC manufactured with a 14nm process allowing for a higher CPU clock of 2.0 GHz compared to the 1.5 GHz frequency used with the original i.MX 8M processor.  i.MX 8M Mini also removes some features (4K video playback, some video interfaces, …) in order to lower the cost of the processor. Companies are still releasing new i.MX 8M SBCs regularly, but we don’t always cover them all since many often do not offer much compared to the competition. But Estone Technology EMB-2237-AI Pico-ITX SBC has some unusual features and options including a Cirrus Logic audio DSP, as well as support for a PoE module and Google Coral M.2 AI accelerator module.   EMB-2237-AI SBC is comprised of a system-on-module and baseboard with the following specifications: Estone SOM-2237 module SoC – NXP i.MX8M Mini Dual or Quad Cortex-A53 @ up to …

CircuitBrains Deluxe is a Tiny, CircuitPython-compatible Module (Crowdfunding)

CircuitBrains Deluxe

There are plenty of boards with Adafruit’s CircuitPython support, but Microchip SAMD51 powered CircuitBrains Deluxe is a little different since it’s a module with castellated holes that make it easy to solder to your own baseboard or integrate into a space-constrained product. CircuitBrains Deluxe specifications: MCU – Microchip/Atmel ATSAMD51J19 32-bit ARM Cortex M4 microcontroller @ 120 MHz with 192 KB SRAM, 512 KB Flash Storage – 8 MB Quad SPI Flash I/Os via 48x through holes and castellated holes around the module GPIO (13 Analog, 2 of which are DAC capable, and 19 Digital) SPI, I²C, UART SWD programming/debug interface USB D- & D+ Power Supply Voltage – 5V Output – Onboard 3.3 V 600 mA Linear Regulator (LDO) connected to 3V3 pin Dimensions – 29 x 29 x 3.5 mm The module comes preloaded with CircuitPython, a fork of MicroPython maintain by Adafruit. You can just connect the board over USB to access the serial console and storage, modify …

ESP32-S2 WiFi SoC Sells for $1, ESP32-S2-WROOM & ESP32-S2-WROVER Modules for $2 and Up

ESP32-S2-WROOM & ESP32-S2-WROVER

Espressif Systems ESP32-S2 was announced in May 2019, before the release of the datasheet and first internal development boards a few months later.  Mass production was delayed due to COVID-19, but earlier this month we reported ESP32-S2 mass production had started and the company has a new ESP32-S2-Kaluga-1 multimedia development board in the works. So it was just a question of time before the processor, modules, and boards become available. Unexpected Maker recently got a development kit with ESP32-S2 final silicon, so I thought maybe I could find ESP32-S2 hardware on Aliexpress. I had no luck finding modules or boards at this time, but one seller is currently selling ESP32-S2 for just $1 per piece, but the trick is that you’d have to purchase 2,000. It’s also about the same price on Digikey. As a reminder, ESP32-S2 SoC is based on a single Xtensa LX7 core clocked at 240 MHz, supports Wi-Fi HT40 @ 2.4 GHz, and provides up to …

MikroElektronika Launches Fusion for ARM & EasyPic MCU Development Boards

fusion for arm

During Embedded World 2020 (EW2020), some companies withdraw their presence, while some were at the event. MikroElektronika presented several new boards and among them Fusion for ARM v8 and EasyPic v8 development boards. While we already wrote about Fusion fo TIVA, we haven’t covered any EasyPic board yet. Development boards from MikroElektronika allow rapid prototyping in the most efficient and effortless way. Fusion for ARM v8 Fusion for ARM v8 belongs to the Fusion family of development boards. It has integrated the world’s first embedded debugger/programmer over WiFi, while the CODEGRIP WiFi license is available as an add-on feature. The board is designed to be used in almost every environment retaining full debugging and programming access. The CODEGRIP currently supports more than 1600 microcontrollers from different vendors. The Fusion board integrates a new MCU card standard. It is a low profile standard where sockets consist of two connectors (male/female) which prevents the wrong insertion. The MCU card has standardized dimensions …

FriendlyELEC SOM-RK3399V2 CPU Module Gets 4GB LPDDR4 RAM Upgrade

SOM-RK3399V2 vs SOM-RK3399

Last year, FriendlyELEC launched SOM-RK3399 system-on-module (SoM) powered by Rockchip RK3399 hexa-core processor combined with 2GB DDR3 memory, 16to 64GB flash, and a built-in WiFi 5 module. Contrary to most SoM’s on the market, SOM-RK3399 could work in standalone mode thanks to two USB-C ports, although it could also be integrated into a carrier board to create a complete development board with more ports and interfaces. The company has now introduced an update with SOM-RK3399V2 CPU module with 4GB LPDDR4 RAM, as well as a small change in the layout for the LED’s and buttons, but the rest of the features remain the same. The company also appears to have changed the way they handle cooling with SOM-RK3399V2 shipping with a heatsink, while SOM-RK3399 cooling was handled by a heatsink + cooling connected to the carrier board. SOM-RK3399V2 specifications: SoC – Rockchip RK3399 big.LITTLE hexa-core processor with 2x Cortex-A72 cores up to 2.0GHz, 4x Cortex-A53 cores up to 1.5GHz, Mali-T864 …
