Challenger RP2040 WiFi board marries ESP8285 with Raspberry Pi RP2040

We’ve already seen Raspberry Pi RP2040 getting WiFi connectivity with boards like Pico Wireless Pack, Wio RP2040 mini, and Arduino Nano RP2040 Connect in ways that do not always make technical and commercial sense as in many cases, the WiFi microcontroller (e.g. ESP32) is more powerful than the Raspberry Pi microcontroller. But Invector Labs’ Challenger RP2040 WiFi board does make more sense, as the company combines Raspberry Pi RP2040 dual-core Cortex-M0+ MCU with an entry-level ESP8285 WiFi microcontroller, and also offers LiPo battery support, all that in the Adafruit Feather form factor. Challenger RP2040 WiFi board specifications: Main microcontroller – Raspberry Pi RP2040 dual-core Cortex-M0+ MCU @ 133MHz with 264KB SRAM Storage – 8MB flash Network microcontroller – Espressif ESP8285 2.4GHz WiFi 4 SoC with 1MB on-chip flash pre-flashed with Espressif’s AT command interpreter, connected to the main MCU over UART at up to 921600 bps; I/Os via Adafruit Feather […]

Minimal Carrier Board for Raspberry Pi Compute Module 4

MinCab is the smallest Raspberry Pi CM4 carrier board ever

Carrier boards for Raspberry Pi CM4 modules are all over the place for routers, NAS, industrial gateways, and more. Here’s another one with the Minimal Carrier Board for Raspberry Pi Compute Module 4, or MinCab, that powers the RPi CM4 module via a USB Type-C port. That’s about all it does, although you would also be able to access some GPIOs, 5V,  3.3V, and GND signals via pads on the carrier board. Specifically, eight GPIOs are accessible with IO14, IO15, IO2, IO3, IO4, IO12, IO13, and IO18. Ivan Kuleshov explains this can be useful for Smart Home systems for instance, but it could be anything that requires WiFI and/or Bluetooth connectivity, a powerful Linux capable processor (as opposed to something like ESP32), and a few I/Os. The MinCab might be a good alternative to the upcoming (and delayed) Raspberry Pi 4 Model A for people wanting to use Broadcom BCM2711 […]

PICO DSP is an Arduino compatible ESP32 development board for audio and DSP applications (Crowdfunding)

ESP32 audio development boards have been around ever since ESP32 boards were introduced starting with Espressif Systems’ own “ESP32-LyraTD-MSC Audio Mic HDK“, and now ESP32 hardware and software have been certified for Amazon Alexa Voice Services. PICO DSP is another ESP32 development board for audio and digital signage processing (DSP) applications. Equipped with a Wolfson WM9878 stereo audio codec, the breadboard-friendly, Arduino compatible board includes two MEMS microphones, audio in and out jacks, a speaker header, plus other audio signals routed to a GPIO header. PICO DSP specifications: SiP – Espressif ESP32-PICO-D4 system-in-package with ESP32 dual-core WiFi 4 & BLE processor, 4MB SPI flash External storage/memory Original Edition – External 64 MB pseudo-static (PSRAM) chip, of which up to 8 MB is currently supported by ESP-IDF. Strawberry Edition – 16 MB of external NOR flash (note: the internal 4MB SPI flash will not be usable after selecting the NOR flash […]

$23 N6110E NVR supports AI features, 10TB SATA drive, up to 10 video channels

Network video recorders (NRV) typically cost a couple of hundred dollars, but in the past, we noted a low-cost, entry-level NVR with a single Ethernet port may sell for under $50. But now, I’ve been made aware that $20 Linux-based NVR’s had shown up on Aliexpress either based on XM8536D processor, or SigmaStar SSR621Q dual-core Cortex-A7 processor.  I’ll look at the N6110E model with the latter that sells for $22.99 plus shipping as it includes an enclosure and is said to support up to 10 channels, as well as AI features such as face & human body detection, “auto tracking” (vehicle tracking?), and mixed-traffic detection. N6110E NVR specifications: SoC – SigmaStar SSR621Q processor/DSP with two Cortex-A7 cores, 256MB DDR3 RAM according to linux-chenxing Video decoding – H.265 , H.264 up to 1x 8MP @ 30 fps, 1x 5MP @ 30 fps, 2x 4MP @ 30fps, 4x 3MP @ 20 fps, […]
