Renesas GR-PEACH mbed Board Features RZ/A1H Processor with 10MB On-chip Memory

Renesas RZ/A1 ARM Cortex A9 processors were unveiled in 2013, and one of the differentiating feature was the large amount of on-chip SRAM with up to 10MB for RZ/A1H model. The following year, Renesas’ RZ/A1 professional development kit, and some RZ/A1H modules were launched, and I’ve now just seen a tweet about Renesas GR-PEACH development board that is mbed compatible, feature Renesas RZ/A1H processor, and happens to be pink. There are actually two models based on the same PCB: GR-PEACH normal without header, and a “WiFi” connector, and GR-PEACH Full with female headers and an Ethernet port. Both basically share the same specifications: SoC – Renesas RZ/A1H ARM Cortex-A9 Core @ 400 MHz with 10MB on-chip RAM, NEON and FPU, and 128KB L2 cache Storage – 8MB FLASH + micro SD slot Connectivity – Normal: Optional BP3595 WiFi module; FULL: 1x 10/100M Ethernet(Microchip LAN8710A); Both: Xbee connector (unpopulated) USB – […]

96Boards Mezzanine Add-on Boards with Sensors, Buttons, Relays, etc.. Are Starting to Show Up

Beside excellent software support, and a great community, the two most popular maker boards on the market, namely Arduino and Raspberry Pi, also have many add-on boards, respectively called Shields and Hats, to expand their user and connect sensors, buttons, displays, and so on… Several Linaro’s 96Boards compliant development board launched last year such as LeMaker Hikey and DragonBoard 410c with support for recent versions of Android and Debian, and recently three Mezzanine add-ons boards, as well as somewhat pricey USB to TLL debug board, have started to show up to make it an even more interesting platform. Linker mezzanine card starter kit for 96Boards The first kit is made by LinkSprite and includes Linker Base Mezzanine Card with several sensors and cables. Eight 4-pin connectors with ADC, UART, I2C, and GPIOs allow you connect the eight sensors ad modules provided with the kit:a button module, a red LED module, […]

Thunderboard Wear is a $75 Smartwatch Development Board by Silicon Labs

A few days ago I watched an ARMDevices.net’s video about an ARM’s smartwatch reference design running mbed OS 3.0, powered by a Silicon Labs EFM32 Giant Gecko Cortex M3 MCU, and promising up to 2 months battery life on a 160 mAh battery. While I could not find the full details about the reference design, I noticed Silicon Labs also launched a development board called Thunderboard Wear, based on the same platform, just quite bigger, and still wearable… (Sort of) Thunderboard Wear specifications: MCU – Silicon Labs EFM32GG995F1024 ARM Cortex-M3 MCU up to 48 MHz with 128 kB RAM,1 MB Flash External Memory – 256 kB external SRAM External Storage – micro SD card slot Display – 128×128 pixel Memory LCD from Sharp Connectivity – Bluetooth 4.1 smart module (Silicon Labs BGM111), upgradeable to Bluetooth 4.2 Sensors Ambient Light Sensing (ALS) and Proximity/Gesture via Silicon Labs Si1141. Optical hear-rate monitoring […]
