- Raspberry Pi 400 “clone” features a 6-core CPU and 4GB RAM
The Raspberry Pi 400’s first clone comes in the form if the Orange Pi 800. This computer and keyboard combo features a Rockchip RK3399 SoC (system on chip), a 6-core 64-bit ARM processor. This SoC utilises the “big/little” architecture and consists of 2x Cortex-A72 high performance cores and 4x Cortex-A53 efficiency cores. Also present on… Continue reading Raspberry Pi 400 “clone” features a 6-core CPU and 4GB RAM - Upcoming Banana Pi BPI-CM4 offers drop-in replacement for Raspberry Pi CM4
Banana Pi have unveiled a work in progress compute module in the same form factor as the Raspberry Pi CM4 but it packs a bigger punch. This new board is called the Banana Pi BPI-CM4 and features an Amlogic A311D SoC, 2 or 4GB RAM and 16GB of storage. The board will also support optional… Continue reading Upcoming Banana Pi BPI-CM4 offers drop-in replacement for Raspberry Pi CM4 - Arm’s Smallest MCU now available on $9 LilyGO development board
Arm HC32L110 MCU The Arm HC32L110 microcontroller packs a single Cortex M0+ core into a tiny 1.56 x 1.44mm package. For context, the Raspberry Pi RP2040 uses two M0+ cores in a 7 x 7mm package. The chip is available for around 60 pence a piece! The chip comes in a compact CSP-16 package (0.35mm… Continue reading Arm’s Smallest MCU now available on $9 LilyGO development board - Ubuntu 22.04 LTS now supported on 2GB Raspberry Pi 4 models
Ubuntu 22.04 LTS was released on the 22nd April 2022 and whilst Ubuntu has been installable on Raspberry Pi 4 models with at least 4gb RAM, only now is Ubuntu officially supported on Pi 4 models with 2GB of RAM. This is due to zswap being enabled by default in Ubuntu 22.04. Zswap is essentially… Continue reading Ubuntu 22.04 LTS now supported on 2GB Raspberry Pi 4 models - SparkFun “Retires” Pro Micro RP2040 – New Version Incoming?
The SparkFun Pro Micro board (SparkFun part number: DEV-17717) has been retired by SparkFun Electronics. However, this does not appear to be the end of the Pro Micro RP2040 as a newer version (DEV-18288) appears to be it’s successor. There is no available stock of the updated part and SparkFun’s datasheets, schematics and GitHub repos… Continue reading SparkFun “Retires” Pro Micro RP2040 – New Version Incoming? - Raspberry Pi Zero 2 W Quick Review
It has been six years since the launch of the Raspberry Pi Zero, a small form factor single board computer. Whilst it got a small refresh in early 2017, with the addition of wireless connectivity, a major update has been a long time coming. Last week the Raspberry Pi Foundation released the Raspberry Pi Zero… Continue reading Raspberry Pi Zero 2 W Quick Review - M5Stamp C3 Released Featuring 32-Bit RISK-V ESP-32C3 MCU
M5Stack’s new development board, the M5Stamp, uses an ESP-32C3 MCU. The ESP-32C3 is a RISK-5 based microcontroller with Wi-Fi 4 and Bluetooth 5 LE connectivity. The onboard RSA-3072-based secure boot and the AES-128-XTS-based flash encryption ensure that devices are connected securely. The ESP32-C3 is supported through Espressif’s open-source ESP-IDF SDK. The M5 Stamp C3 comes… Continue reading M5Stamp C3 Released Featuring 32-Bit RISK-V ESP-32C3 MCU - HardKernal discontinues ODROID-H2+ single board computer
The $119 single board computer based on Intel’s Quad-Core J4115 has been discontinued due to ongoing supply chain issues. A statement on the ODROID-H2+’s product page reads: It has not been possible for us to clearly establish the future availability of a main component due to the global chip shortages, we have therefore decided to… Continue reading HardKernal discontinues ODROID-H2+ single board computer - New T-Head RVB-ICE Development Board Features Dual-Core RISK-V Processor
Following the launch of the Nezha single board computer (SBC) last year (article from hackster.io), T-Head and Alibaba are back at it with another linux-capable SBC. The RVB-ICE is a brand new board (available to pre-order) which features two C910 RISC-V cores running at up to 1.2GHz. Packed alongside this CPU is a Vivante GC8000UL… Continue reading New T-Head RVB-ICE Development Board Features Dual-Core RISK-V Processor - SparkFun’s New Breakout Board Brings 60GHz Pulsed Radar To The Raspberry Pi
SparkFun’s new $60 breakout board brings accurate distance-sensing to the Raspberry Pi. A111 Breakout Board is available for $59.95 from SparkFun. SparkFun A111 Pulsed Radar breakout board features the A111 radar chip, with integrated antenna. SparkFun state the primary use case of the pulsed coherent radar (PCR) is distance sensing. However, the board also supports… Continue reading SparkFun’s New Breakout Board Brings 60GHz Pulsed Radar To The Raspberry Pi
