Microchip Introduces $11 RN2483 & RN2903 LoRa Modules and $70 LoRa Evaluation Kits for IoT & M2M Applications

LoRa is one of those long range low power WAN standards used for the machine to machine (M2M) and Internet of things (IoT) applications. I already featured a Semtech Lora module here with a line-of-sight range of up to 20 to 30km, and the company has just partnered with STMicro to deploy LoRa solutions, but today, I’m going to have a look at Microchip Lora modules and development kits that I discovered in the company’s Micro Solutions Nov/Dec 2015 publication. The company has launched two modules for the European and North American markets with respectively RN2483 LoRa 433/868 MHz R&TTE Directive Assessed Radio Modem and RN2903 915 MHz North American modem. Apart from the different frequencies, both modules have similar features: On-board LoRaWAN Class A protocol stack Tx/Rx Power RN2483 – 40 mA (14dBm, 868MHz) Tx, and 14.2 mA Rx @ 3.6V RN2903 – 124 mA Tx max, and 13.5 mA […]

LeMedia is a Linux Distribution based on Debian and Kodi 15.2 for Actions Semi S500 Processor

LeMaker has recently released LeMedia, a Linux distribution based on Kodi 15.2 and Debian Jessie for their Guitar board powered by Actions Semi S500 quad core Cortex A9 processor, also found in Lemon Pi, ActDuino-S500 and Roseapple Pi boards. The good news is that H.264 and MPEG4 hardware video decoding is implemented, as well as PowerVR SGX544 GPU 3D acceleration. This is an early version and while IR receiver, WiFi, HDMI and LCD output, and audio are working, the company explained that HDMI support may be flaky, USB 3.0 speed is not optimal, and touchscreen support had to be disabled. They also included a “LeMedia Settings” in the image to have a similar experience as “RaspBMC Settings”. The images for booting from SD card or eMMC can be downloaded here. It’s quite likely they only work on LeMaker Guitar board, and I could not find the Linux 3.10.37 kernel, nor […]

LeMaker Hikey 96Boards Development Board Comes with 1 to 2GB RAM, Sells for $75 and Up

Hikey was the first 64-bit ARM development board compliant with 96Boards specifications, and supported by Linaro. Availability always seemed to be an issue however, and pricing was set to $129. But Lemaker, the makers of Banana Pi boards, recently joined Linaro, and they’ve built a lower cost version of the Hikey board, still featuring Hisilicon Kirin 620 octa-core ARM Cortex-A53 processor, but with 1GB and 2GB RAM versions, priced respectively at $75 and $99. LeMaker Hikey board specifications: SoC – HiSilicon Kirin 620 octa core Cortex A53 processor @ 1.2 GHz with ARM Mali-450MP4 GPU System Memory – 1 or 2 GB LPDDR3 @ 800 MHz Storage – 8GB eMMC + micro SD slot Video Output / Display – HDMI up to 1080p, MIPI-DSI interface Connectivity – 802.11 a/b/g/n Wi-Fi, Bluetooth 4.1 LE (WL1835MOD module) USB – 2x USB 2.0 host ports, 1x micro USB OTG Camera – MIPI CSI […]

HummingBoard Gate Boards Add a mikroBUS Socket to Support MikroElektronika Click Boards

SolidRun already released HummingBoard-Base, HummingBoard-Pro, and HummingBoard Edge previously, but the company has now launched another version of their Freescale i.MX6 based boards with HummingBoard Gate that adds a mikroBUS socket to support over 150 add-on boards – called Click Boards – made by MikroElektronika. HummingBoard Gate specifications: SoC – Freescale i.MX6 Solo, Dual Lite, Dual, or Quad with Cortex-A9 cores @ 1 to 1.2 GHz System Memory – Up to 4GB DDR3 Storage – Micro SD slot Connectivity – Gigabit Ethernet (limited to 470Mbps), optional WiFi/Bt module Video Output – HDMI output, MIPI-DSI connector Camera – MIPI CSI-4, parallel camera USB – 4x USB 2.0 ports Expansion mPCIe slot with SIM card holder 36-pin GPIO header mikroBUS click interface Misc – Reset button, RTC with battery Power – 7-36V, 5.5mm jack Dimensions – 102 x 69 mm As usual, the board is comprised of a baseboard and a microSOM, […]

LeMaker Guitar is a $25 Single Board Computer Powered by Actions Semi S500 Processor

LeMaker, better known for the Banana Pi, has recently unveiled three boards at an event in China: LeMaker Bass – a 96Boards compliant board powered by Actions Semi S900 quad core processor LeMaker Piano – An industrial grade single board computer based on Freescale i.MX6 Solo, Dual or Quad LeMaker Guitar – A low cost board powered by Actions Semi S500 processor There are plenty of Freescale i.MX6 industrial boards on the market, and LeMaker Bass appears to be the previously announced Bubblegum-96 board now supported by Lemaker, so I’m going to focus on LeMaker Guitar in this post. It’s good to see at least one company dropped the “fruit + pi” theme for their new boards… The Guitar board is comprised of a system on module (SoM), and a baseboard. The SoM comes with the following technical specifications: SoC – Actions Semi S500 quad core Cortex A9r4 processor @ […]

Relative Performance of ARM Cortex-A 32-bit and 64-bit Cores

Many people assume newer processors will be faster, or that 64-bit processor will provide a performance boost compared to 32-bit processors, but the reality can be quite different, and I’ve decided to have a look at ARM Cortex-A cores using ARMv7 (32-bit) and ARMv8 (64-bit) architecture, and see what kind of integer performance you can expect from each at a given frequency. To do so, I’ve simply use DMIPS/Mhz (Dhrystone MIPS/Megahertz) values listed on Wikipedia. Drystone benchmark has no floating-point operating, so it’s a pure integer benchmark. I’m only looking at ARM core here, and once integrated in an SoC, other parameters like memory bandwidth, amount of cache,  GPU, etc.. will greatly affect the overall system performance. The figure above are per MHz, and it does not mean for example that a Cortex A5 processor will be slower than a Cortex A7 processor, as can be seen by the comparison […]
