Embedded Artists launches 1GHz NXP i.MX RT1176 Crossover MCU module and devkit

Microcontrollers used to be those cute little chips clocked at 8 MHz, but it’s now common to have MCUs clocked at one or two hundred Megahertz, and with Cortex-M7 cores, several hundred Megahertz is now possible, and NXP even pushed the limit to one Gigahertz with their i.MX RT1170 series of Cortex-M7/M4 Crossover MCUs announced over a year ago. Embedded Artists has now made a computer-on-module and a corresponding devkit based on NXP i.MX 1176 Crossover MCU clocked at one Gigahertz. iMX RT1176 uCOM MCU module delivers up to 6468 Coremarks, comes with up to 32MB SDRAM, 16MB QSPI flash, optional WiFi and Bluetooth, and various peripherals in a tiny 45x42mm form factor. iMX RT1176 uCOM module Specifications: SoC – NXP i.MX RT1176 processor with Cortex-M7 core up to 1 GHz/800MHz (Commercial vs industrial), Cortex-M4 core up to 400/200 MHz, 2MB internal SRAM, 2D GPU with OpenVG 1.1 support and […]

Qomu Cortex-M4F & FPGA USB board is programmable with Symbiflow open-source toolchain (Crowdfunding)

We’ve seen several tiny “omu” USB boards that are the size of a USB connector in the past, starting with Tomu based on Silabs EFM32 Arm-Cortex-M0+ MCU, then Fomu enabling Python programming and RISC-V softcore on a Lattice ICE40 FPGA, and finally Somu FIDO2 security key. There’s now the new Qomu board based on Quicklogic EOS S3 Cortex-M4F MCU with embedded FPGA. Just like its predecessor, the board almost completely fits in a USB connector except for the touch pads, and also happens to be programmable with Symbiflow that dubs itself as the “GCC of FPGAs”, as well as other open-source tools. Qomu specifications: SoC – QuickLogic EOS S3 Arm Cortex-M4F MCU @ up to 80 MHz with 512 KB memory, embedded FPGA with 2,400 effective logic cells and 64 Kbits of embedded RAM Storage – 16 Mbit flash Misc – Four capacitive touch pads, 1x RGB LED Power – […]

Open hardware Raspberry Pi Pico VGA, SD Card, and Audio demo board to support QVGA video playback

Abhishek recently posted an overview of Raspberry Pi RP2040’s two PIO blocks with examples in C and Micropython using some PIO assembler code. He used some basic examples like blinking an LED, but the Raspberry Pi Foundation also mentioned the programmable IO could be used to drive a VGA display, read and write data from a MicroSD card at reasonable speeds, and so on. However, the Raspberry Pi Pico does not have any of those interfaces, and it would be nice to have a board that does. It turns out there’s such a board in “Chapter 3. The VGA, SD Card & Audio Demo board for Raspberry Pi Pico” of “Hardware Design with RP2040.pdf” document. It will be sold as the “Pimoroni Pico VGA Demo Base” board for 19.50 GBP inc. VAT (about $22 US ex. VAT), but since the KiCad hardware files are open-source, I’d assume other companies may […]

Third-party Raspberry Pi RP2040 boards from Arduino, Adafruit, Sparkfun and Pimoroni

I’ve just written about the launch of the Raspberry Pi Pico board and Raspberry Pi RP2040 MCU, which, as I explained in the announcement, could be used with third-party boards, but what I was not made aware during the embargo was that RP2040 boards were already being worked on, and other companies jointly announced their own custom Raspberry Pi Pico compatible board with Adafruit, Arduino, Pimoroni, and Sparkfun joining the party. Arduino Nano RP2040 Connect Board When I first wrote about Raspberry Pi Pico, I really saw it would be a competitor to Arduino boards, but instead Arduino and Raspberry Pi joined hands to design Arduino Nano RP2040 Connect with the board including 16MB external SPI flash, a u-blox NINA WiFi & Bluetooth module, an STMicro MEMS sensor with 9-axis IMU and microphone, and the ECC608 crypto chip. That obviously means Arduino Core will also support the new RP2040 MCU. […]

$4 Raspberry Pi Pico board features RP2040 dual-core Cortex-M0+ MCU

The Raspberry Pi Foundation introduced the Linux-capable Raspberry Pi board in 2012 to teach programming and computers. Since then, the company has introduced models with faster processors, more memory, faster interfaces, culminating with the launch of Raspberry Pi 4 in 2019. The board also comes with a 40-pin header to teach electronics, but relying on a Linux SBC to blink a LED, gather data from sensors, or controlling servos is a bit over the top. So the Raspberry Pi Foundation decided to create their own MCU board called Raspberry Pi Pico powered by RP2040 dual-core Cortex-M0+ microcontroller designed in-house by the foundation. Raspberry Pi RP2040 microcontroller Before we look at the board, let’s check out RP2040 specifications highlights: Core – Dual Cortex M0+ cores up to 133 MHz (48MHz default) Memory – 264 kB of embedded SRAM in 6 banks Peripherals 30 multifunction GPIO 6 dedicated IO for SPI Flash […]
