Arduino Nano RP2040 Connect WiFi & Bluetooth board launched for $25.50

Arduino Nano RP2040 Connect without headers

The Arduino Nano RP2040 Connect board was announced the day of Raspberry Pi Pico launch as one of the third-party boards featuring Raspberry Pi RP2040 dual-core Cortex-M0+ microcontroller. At the time all we had was renders of the board, later on, the company showcased some mass product photos, and then released Arduino Core mbed 2.0 for the board last month. But it’s only today that it has become possible to purchase Arduino Nano RP2040 Connect board for $25.50 on Arduino store with headers. Nano RP2040 Connect specifications: MCU – Raspberry Pi RP2040 dual-core Cortex M0+ microcontroller @ 133 MHz with 264 kB of embedded SRAM Storage – 16MB Flash IC (AT25SF128A) Connectivity – WiFi 4 & Bluetooth LE via Nina W102 uBlox module (Yes, that’s an ESP32 module.) USB – Micro USB port I/Os via 2x 15-pin headers (through and castellated holes) 20x digital I/O pins, 20x PWM pins, 20x […]

Why you should request open-source software for your IoT devices

PineTime open-source software Gadgetbridge

I usually think of open-source hardware and/or software are enabling skilled people to more easily fix bugs, improve on the design, get feedback from the community, etc… But in a world where IoT devices become more prevalent, there’s another reason why you should request open-source software: Long term support. What made me think about are two things. The first one if that I own WeLoop Hey 3S smartwatch, which I love and wear since March 2018. That’s quite a feat since most cheap devices I own often only last a few months or a year or so. I’m also used to the watch face and Weloop app interface. So what’s the problem exactly? WeLoop company closed on December 31, 2019, and while the app worked fine for about a year after that, recently I have been unable to login to the app to access my data and/or update settings for […]

HEGduino V2 supports fNIRS and Blood-Flow Monitoring (Crowdfunding)

AlasKit has launched a crowdfunding campaign on Crowd Supply for HEGduino V2. The device features noninvasive optical imaging through fNIRS (Functional near-infrared spectroscopy), apart from its brain blood flow monitoring functionality. We saw the previous version of the HEGduino in September 2019 which only supported blood flow monitoring. But the HEGduino V2 also monitors breathing, heart rate, and skin temperature. HEGduino V2 has a MAX86141 optical pulse oximeter cum heart-rate sensor for incorporating Heart Rate Variability (HRV) training. It also allows breath and skin temperature monitoring. The sensor has a specification of 2×4096 SPS sensing with a 19-bit resolution which is a bit higher than its previous version. As HEGduino V1 had an 860 SPS sensing with a 16-bit resolution. However, the practical application observes even lesser values for HEGduino V1. Setup of HEGduino V2 The device also comes with an ESP32 breakout board with rechargeable battery support. The board […]

S805X2 AV1 Android TV dongles and TV boxes are starting to show up

Amlogic S805X2 AV1 capable processor was first teased as an update to S805X and S805Y Full HD TV box processors in 2019 with very little details. But companies have started to list some S805X2 based Android dongles and TV boxes. That means we also have additional details for the processor, and we’ll look into SDMC DV9035 TV box and SEI Robotics SEI103 dongle, neither of which should be sold to end-users, but instead OEM’s or content providers. SDMC DV9035 S805X2 TV box Specifications: SoC – Amlogic S805X2 quad-core Arm Cortex-A35 processor with Mali-G31 MP2 GPU System Memory – 1GB DDR4 Storage – 8GB eMMC flash Video Output – HDMI up to 1080p60 with HDR support Video Codecs – AV1, VP9, H.265, H.264 High-dynamic Range – HDR 10, HLG, HDR10+Optional Connectivity 10/100M Ethernet Dual-band 2.4GHz/5GHz 802.11a/b/g/n/ac WiFI 5 with optional 2×2 MIMO, Bluetooth 4.2 or higher USB – 2x USB 2.0 ports DRM – […]

US516P6 RISC microcontroller powers offline voice assistant modules

I recently wrote about a Linux microwave oven with a built-in voice assistant, and somebody mentioned a quad-core SoC was overkill, and instead US516P6 microcontroller designed for offline voice commands would be a better fit. It’s all good, but finding information about Unisound US516P6 proved to be quite a challenge with not much public information, and most in Chinese. But then I noticed Wireless Tag WT516P6Core offline voice module, and since I have contact with the company I managed to get a few more details, notable with regards to the development tools. US516P6 module specifications: MCU – Unisound US516P6 RISC microcontroller (likely Andes NDS32 based) @ 240 MHz with FPU, DSP instruction, FFT accelerator, 242KB SRAM, 2MB flash Audio – Built-in power amplifier I/Os – 12 castellated holes with UART, GPIO, microphone input, speaker output, VCC, and GND Power Supply – Built-in 5V to 3.3V, 3.3V to 1.2V LDO to […]
