Olimex Launches NB-IoT DevKit Based on Quectel BC66 Module for 19 Euros

There are three LPWAN standards currently dominating the space LoRaWAN, NB-IoT, and Sigfox. In a recent presentation, Olimex explains NB-IoT (aka LTE Cat NB1) offers several advantages over LoRaWAN and Sigfox which include: Higher speeds of up to 25.5 kbps (UL/DL) Single GSM base station can handle up to 100 000 NB-IoT nodes Single GSM base station can cover up to 10-100km range in rural environments, and 1 to 10km in urban settings Lasts up to 10 years on a Lithium 3V battery if less than 200 bytes are sent per day The main disadvantage they listed was operator dependence, as you rely on the operator for coverage, and anything related to connectivity. In Bulgaria in particular, they found out it was not easy to get an NB-IoT SIM card activated, and the operator may shut you off without notice. For reference here in Thailand, last time I checked I […]

Arduino MKR WAN 1310 LoRa Board Gets HW Security, Longer Battery Life and a 2MB SPI flash

Two year ago Arduino launched MKR WAN 1300 board powered by Arduino Zero compatible Microchip Atmel SAMD21 32-bit ARM Cortex M0+ MCU and a Murata CMWZ1ZZABZ LoRa module based on Semtech SX1276 and STMicro STM32L microcontroller. The company has now announced a new improved LoRa board – MKR WAN 1310 – with lower power consumption thanks to a new battery charger , a 2MB SPI flash which enables data logging and other OTA (Over-the-Air) functions, and a crypto chip that can securely store credentials and certificates. Specifications: MCU – Microchip Atmel SAMD21 32-bit ARM Cortex M0+ MCU @ 48 MHz with 32 KB SRAM, 256 KB flash (8KB for bootloader) External Storage – 2MB SPI flash Digital I/O Pins – 8x digital I/Os, 12x PWM, UART, SPI, and I2C, 8x external interrupts Analog Pins – 7x analog inputs (8/10/12-bit ADC), and 1x analog output (10-bit DAC) DC Current per I/O […]

Novasom M7+ SBC Adds FFC HDMI Connector, USB & RS-485 Headers, Improves on Raspberry Pi 3 SW Compatibility

We previously wrote about Novasom M7 Rockchip RK3328 SBC being promoted as a drop-in replacement for Raspberry Pi 3 in industrial projects. That’s despite the different port arrangement, and instead, the company bases the claim on the availability of the 40-pin header, mounting holes matching RPI 3 board design, as well as software compatibility thanks to a library that allows customers to re-use the code written for Raspberry Pi boards. Based on feedback from customers, the company has made some changes to their design and launched Novasom M7+ SBC, and made several improvement to the software to be even more compatible with Raspberry Pi 3 board. Specifically there are five changes: Ability to power the board via the USB type-A port (5V) as an alternative to the 12V power barrel jack Stronger Backlight Driver for display up to 6A @5V) t FFC cable for HDMI output – The dimension of […]

NanoPI NEO2 Black Allwinner H5 SBC Adds an eMMC flash Module, Up to 1GB RAM

NanoPi NEO2, now called NanoPi NEO2 LTS, is a great little Allwinner H5 SBC designed for server/headless applications with Ethernet & USB ports, as well as I/O headers. FriendlyELEC is now about to launch a new variant called NanoPi NEO2 Black with the same form factor and Allwinenr H5 64-bit Arm SoC, but adding an eMMC flash module, supporting up to 1GB RAM, modifications to the I/O headers, and featuring a black PCB instead of the blue PCB found in NEO2-LTS. NanoPi NEO2 Black SBC specifications with changes in bold or stricken-through: SoC – Allwinner H5 quad-core Cortex A53 processor with an ARM Mali-450MP GPU System Memory – 512 MB or 1GB DDR3 Storage – MicroSD card slot, eMMC flash module connector Connectivity – Gigabit Ethernet (via RTL8211E-VB-CG chip) USB – 1x USB 2.0 host port, 1x micro USB OTG port, 2x 1x USB via headers Expansion headers 10-pin header […]

Wio Lite RISC-V WiFi Board with ESP8266 Module Launches for $6.9

Released this summer, GigaDevice GD32V generated a lot of buzz, as a cheap general-purpose 32-bit RISC-V MCU, and soon after the $5 Longan Nano development board with LCD display and enclosure was launched to the market. However, many applications benefit or require some network connectivity with WiFi. Espressif Systems is a founding member of the RISC-V Foundation, so RISC-V WiSoCs (Wireless SoCs) are coming, but AFAIK none of those are available yet. In the meantime, Seeed Studio has launched Wio Lite RISC-V board which brings WiFi connectivity to GD32V MCU through an ESP8266 WiFi module. Wio Lite specifications: MCU – Gigadevice GD32VF103CBT6 RISC-V (rv32imac) microcontroller @ 108 MHz with 128KB Flash, 32KB SRAM Wireless Module – ESP8266 WiFi Wio Core with 802.11b/g/n/ WiFi 4 connectivity Storage – MicroSD card slot USB – 1x USB Type-C port for power and programming Expansion – I/O headers for GD32 MCU, I/O header for […]

Rock Pi 4C SBC to Support Dual Display Setups via micro HDMI and mini DP Ports

Rockchip RK3399 powered Rock Pi 4 SBC was introduced at the end of 2018 and followed nearly exactly Raspberry Pi 3 Model B form factor just with a more powerful processor, GPU, as well as more memory depending on which model you purchase. But in June 2019, the Raspberry Pi foundation launched Raspberry Pi 4 SBC with a much faster processor and many of the same ports as its predecessor except for support for two HDMI displays via micro HDMI ports. Radxa has now followed suit with Rock Pi 4C which offers two modern video outputs, but with a twist as the upcoming SBC combines one micro HDMI port with one mini DP port. Rock Pi 4C was introduced at the XDC 2019 conference where open-source graphics developers meet, and Radxa was a “supporter”. The company explains Rock Pi 4B uses RK3399’s USB type-C controller for the two USB 3.0 […]

NanoPi M4V2 Metal Case Kit Review – Part 1: Unboxing and Assembly

Earlier this month FriendlyELEC released two new products namely NanoPi M4 metal case with heatsink and optional NVMe SSD adapter, and NanoPi M4V2 SBC, a minor upgrade to the original Rockchip RK3399 powered NanoPi M4 board with faster LPDRR4 memory, the addition of power & recovery buttons, and microphone input is now inside the audio jack instead of solder pads. I received both this weekend, in the first part of the review I’ll show the items part of the package and then show how to assemble the kit. In the second part, I’ll focus on the new features of the board like memory bandwidth, as well as the thermal performance of the complete solution in both Android and Linux. Unboxing Instead of one kit, I actually received two. One kit basically includes NanoPi M4V2 board with internal antennas (which we won’t use here), and the metal case which comes with […]
