GR-LYCHEE Development Board to Combine Renesas RZ/A1LU Processor, ESP32 Module, and a VGA Camera
Japanese semiconductor vendors have mostly stayed away from the maker market, at least outside Japan, as most people would be hard-pressed to come up with a hobbyist development board powered by processor or micro-controller from Toshiba, Sony, Renesas or other Japanese companies, despite the three aforementioned names being in the top 20 semiconductors companies. I can only remember having written about Fujitsu F-Cue 96Boards, as well as Renesas GR-PEACH mbed board since I started this blog 7 years ago. Renesas seems to be the only company to have a real community behind with their “Gadget Renesas” pink-colored development boards, and the latest and seventh board is GR-LYCHEE powered by Renesas RZ/A1LU ARM Cortex-A9 processor, and equipped with a WiFi & Bluetooth module, and a camera. Renesas GR-LYCHEE board preliminary specifications: Micro-processor – Renesas RZ / A1LU (R7S721030VCFP 176-pin QFP) ARM Cortex-A9 Processor @ 384 MHz with 3MB on-chip SRAM Storage […]
Microchip based Orange LoRa Explorer Kit Connects to Orange’s own LoRaWAN Network
You’d think Telecom operators with all infrastructure in place would focus their IoT efforts on LTE Cat M1 or LTE Cat NB-IoT, but Orange has setup its own LoRa network in France with the aim of achieving national coverage by December 2017, at which time they’ll also test interconnection and roaming with other European operators. The company has also launched the LoRa Explorer Kit based on Microchip solutions, and designed by SODAQ. Orange LoRa Explorer Kit specifications: MCU – Microchip Atmel SAMD21 ARM Cortex M0+ MCU @ 48 MHz with 256KB flash, 32KB RAM, up to 16KB EEPROM by emulation Storage – 4Mbit serial flash (Microchip SST25PF040C) Connectivity Microchip RN2483A LoRa module + PCB antenna Microchip RN4871 Bluetooth 4.2 module (BLE) with ceramic antenna Security – Microchip ATECC508A1 crypto chip to securely store LoRa keys. USB – 1x micro USB port for charging and programming Expansion – “Arduino M0” compatible headers with 10-bit […]

Review of Wio Tracker with GPS, Bluetooth 3.0 and GSM Connectivity
Wio GPS – also called Wio Tracker – is an Arduino compatible board based on Microchip Atmel SAMD21 MCU with GPS, Bluetooth, GSM/GPRS connectivity, as well as several Grove connectors to connect sensors and modules for your IoT project. SeeedStudio sent me a sample for evaluation, so I’ve tested it, and reported my experience below by testing some of the Arduino sketches. Wio Tracker Unboxing All I got in the package was Wio GPS tracker v1.1 board. The top includes the Atmel MCU, an RGB LED, a microphone and 3.5mm AUX jack to make phone calls, a user and power button, a micro USB port for power and programming, a small 2-pin connector for a battery, and 6 Grove connectors for digital, serial, I2C and analog modules. The other side of the board comes with Quectel MC20 module that handles Bluetooth, GPS and GSM, a dual use micro SD card […]
Apple Opens HomeKit Accessory Protocol Specification to Non-Commercial Projects
HomeKit is a software framework that allows Apple users to control smart devices with their iPhone or iPad. But so far, you had to become an MFI licensee to design a HomeKit compatible device, you product had to be tested by Apple, and – according to a story on Hackster.io – also required a special cryptographic chip for authentication. Developers creating commercial devices still need to become an MFI license, but Apple has now opened HomeKit Accessory Protocol Specification for non-commercial projects, meaning you can now use the Framework on Arduino, ESP8266 boards, Raspberry Pi, and other development boards using software authentication. You could already use HomeKit on Raspberry Pi board previously using HomeBridge, but the advantage now is that you don’t need to breach Apple’s terms and conditions, and you can talk directly to your phone without the need for a bridge. If you want the specifications got to […]
