Olimex ESP32-ADF Board is Made for Smart Speakers, Internet Radios, VoIP Phones, and More

We’ve already covered several (smart) audio boards based on ESP32 WiSoC, including the Espressif’s own ESP32-LyraTD-MSC Audio Mic HDK, as well as third party boards such as TTGO TAudio or Seeed Studio ESP32-A1S all compatible with the company’s ESP-ADF (Audio Development Framework) compatible with Baidu DuerOS, Google Assistant and Amazon Alexa. Olimex ESP32-ADF adds another ESP32 audio option, and AFAIK the first one that is open source hardware, with two speakers, and a dual-microphone that enable projects such as Alexa smart speaker, internet radio receiver, or SiP VoIP phone. Olimex ESP32-ADF specifications: Wireless Module – ESP32-WROVER-B with 8MB PSRAM, 4MB Flash, WiFi 4 and Bluetooth 4.2 LE Audio Stereo microphones Stereo 2x3W speakers with amplifier Audio output jack Display – UEXT connector for optional 2.8″ LCD display USB – 1x micro USB port for power supply and programming Misc – IR receiver, 4x touch buttons, 3x tactile buttons Build-in programmer […]

Amlogic S905X2 vs S905X3 – Features Comparison

Despite Arm claiming Cortex-A55 core would bring some performance improvements, we’ve recently seen actual Amlogic S905X3 benchmarks show the performance compared to Amlogic S905X2 Arm Cortex-A53 is almost identical (3% improvement for S905X3 CPU, 9% for the GPU). So Amlogic S905X3 TV box processor must differentiate itself from its predecessor by its additional features, and while we published the detailed specifications of Amlogic S905X3 processor a few months ago, we did not provide a side-by-side comparison table just yet. So here’s one courtesy of SDMC (with some corrections). SoC Amlogic S905X2 Amlogic S905X3 CPU 4x Arm Cortex-A53 @ 1.80 GHz 4x Arm Cortex-A55 @ 1.91 GHz Neural Network Accelerator N/A Optional 1.2 TOPS NNA GPU Mali-G31 MP2 with OpenGL ES 3.2, Vulkan 1.0, and OpenCL 2.0 Always-on MCU Cortex-M3 & Cortex-M4 (Optional ) Cortex-M3 & Cortex-M4 DDR DDR3-2133 /DDR3L-2133 / DDR4-2666 /LPDDR3-2133 /LPDDR4-3200 SDRAM up to 4G DDR3-2133 /DDR3L-2133 / […]

Icarus IoT Board Features nRF9160 GPS + NB-IoT SiP in Adafruit Feather Form Factor

The new Icarus IoT board from Actinius, uses the Nordic nRF9160 SiP, a powerful yet low power system in a package designed for use with GPS and LTE-M & NB-IoT cellular data, also found in Ruuvi node which we covered a few months ago. The board’s purpose is for mobility and ease of project tracking anywhere, and can be found in application scenarios such as fleet management and security, cargo tracking, or asset monitoring, and many more. The board has power inputs for solar panel, USB or LiPo/Li-Ion Battery, which widens the boards mobile nature, and on-site, in-the-field capability. Since the form factor follows Adafruit Feather, the Icarus board benefits of additional component options for prototyping and DIY electronics projects. The nRF9160, by Nordic Semiconductor, is a SiP (System in a Package) that carries an extensive line of embedded software and hardware. As we had reported the nRF9160 SiP low-power […]

MikroTik is Launching a new set of LoRa products this summer

MikroTik, the Latvian network equipment manufacturer, is reportedly launching a new set of IoT LoRa devices this summer. MikroTik who has been traditionally known for its wireless technologies, especially products related to wireless networking like routers, switches, antennas, and others, is going full fledged in support of LoRa network, the promising LPWAN technology for IoT applications. MikroTik announced a new LoRa based Gateway product in Vienna back in March 2019 during the MUM Europe MikroTik User Meetings. It was a combination of a wAP 2GHz outdoor AP with a LoRaWAN card inbuilt inside and will work just like every other LoRa gateways out there. The gateway is expected to support both public and private network server. According to MikroTik, they promised to cut down the high-end prices of LoRa gateway: We will undercut that price be a very very big difference, so our LoRa gateway will much much more affordable than […]

Docker Pi IoT Node(A) Adds LoRa, GPRS and GPS to Raspberry Pi Board

The Docker Pi IoT Node(A) is the latest addition to the Docker Pi series of modules meant to enhance IoT capability and expand on the Raspberry Pi family of SBCs. Although it is mountable on the Raspberry Pi SBC, the HAT form factor allows it to be used with other similar single board computers such as Rock64 board. The Docker Pi IoT Node(A) supports GPS/BDS (Beidou), GSM, and LoRa. The add-on board interfaces to the host over I2C, in order to control LoRa & GSM connectivity, as well as the GPS/BDS module through SC16IS752 chip. There are a number of code examples and instructions that can be found on the Wiki. The unit can also be controlled directly without programming, and all the GPIO pins are extended so the board can stack on other HAT compatible boards, in appropriate layers. Specifications GPRS section Low power consumption, standby sleep current <1mA […]

Checking Out Machine Check Exception (MCE) Errors in Linux

I recently reviewed ODROID-H2 with Ubuntu 19.04, and noticed some errors messages in the kernel log of the Intel Celeron J4105 single board computer while running SBC-Bench benchmark:

[180422.405294] mce: [Hardware Error]: Machine check events logged

I did not know what do make of those errors, but I was told I would get more details with mcelog which can be installed as follows:

sudo apt install mcelog

1	sudo apt install mcelog

There’s just one little problem: it’s not in Ubuntu 19.04 repository, and a bug report mentions mcelog is not deprecated, and remove from Ubuntu 18.04 Bionic onwards. Instead, we’re being told the mcelog package functionality has been replaced by rasdaemon. But before looking into the utilities, let’s find out what Machine Check Exception (MCE) is all about from ArchLinux Wiki: A machine check exception (MCE) is an error generated by the CPU when the CPU detects that a hardware error or failure has occurred. Machine check exceptions (MCEs) can occur for a variety […]
