BL-63B – A smaller BL602 IoT module that sells for $1.5

Bouffalo Labs BL602 is a low-cost, low-power RISC-V microcontroller that offers 2.4 GHz WiFi and Bluetooth 5.0 LE connectivity for IoT projects for about the price of ESP8266. We first discovered it last year, together with a development board. Pine64 created its own PineCone board fitted with the $2 PineNut module, and some reverse-engineering work has started on BL602 SDK. But there’s now another smaller BL602 module with “Machine Intelligence” (that’s the company name) BL-63B that sells for $1.5 on Taobao in China, as well as on LCSC Electronics albeit you’d need to purchase 1000 pieces to get that price, and single-unit pricing is currently $2.5. BL-63B WiFI & BLE module specifications: SoC – Bouffalo Labs BL602 32-bit RISC-V processor @ up to 192 Mhz with 276KB RAM, 128KB ROM, 1Kbit eFuse, WiFi and BLE Storage – 2MB flash Wireless 2.4GHz 802.11b/g/n WiFI 4 1×1 SISO up to 65 Mbps […]

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

N6110E SigmaStar SSR621Q network video recorder

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, […]

ESP32-H2 RISC-V WiSoC announced with Zigbee 3, Thread, and Bluetooth LE 5.2

Just a few days ago, we noted ESP32-H2 802.15.4 & BLE RISC-V SoC had shown up in the source code, and tried to derive specs and a block diagram from the info seeing it was similar to ESP32-C3, but swapping the WiFi radio for an 802.15.4 radio. We don’t need to guess anymore, as Espressif Systems has just announced ESP32-H2 RISC-V WiSoC with support for Zigbee 3.x, Thread 1.x through the 802.15.4 radio, as well as Bluetooth LE 5.2. So overall it’s very close to what we discussed from the information in the source code with ESP32-H2 highlights including: CPU – 32-bit RISC-V core (at up to 96 MHz) RAM – 256 KB SRAM Storage – External flash support Wireless connectivity IEEE 802.15.4 radio with Zigbee 3.x and Thread 1.x support, Matter protocol Bluetooth 5.2 (LE) radio designed in-house, with support for direct connection, Bluetooth Mesh, Bluetooth LE Audio Future […]

STEVAL-VOICE-UI Amazon qualified Alexa Smart Home evaluation kit is based on STM32H7 MCU

We’ve already covered plenty of Amazon-qualified development kits working with Alexa Voice Services. But here’s another one with STEVAL-VOICE-UI evaluation kit making it to the list of Smart Home Dev Kits, which Amazon describes as “reference designs for creating smart home products such as light switches, thermostats, or Wi-Fi routers”. STEVAL-VOICE-UI voice user interface (VUI) evaluation kit features an STMicro STM32H7 Arm Cortex-M7 microcontroller with 2 MB embedded flash, 1 MB embedded SRAM, 2.4 GHz Wi-Fi, and a microphone array with three MEMS microphones, as well as a loudspeaker, and some buttons and LEDs. STEVAL-VOICE-UI key features specifications: Microcontroller – STMicro STM32H753VIT6E Cortex-M7 MCU @ up to 550 MHz with 2 MB flash, 1 MB SRAM Connectivity – 2.4 GHz Wi-Fi subsystem (Murata 1DX module) coupled to 2MB NOR flash (ISSI IS25LP016D) Audio 3x MP23DB01HP MEMS microphones with 36 and 30 mm spacing FDA903D class D digital input automotive audio […]

ESP32-H2 Bluetooth LE & 802.15.4 RISC-V SoC shows up in ESP-IDF source code

Espressif Systems is working on yet another RISC-V chip with ESP32-H2 SoC offering Bluetooth LE and 802.15.4 connectivity showing up in the ESP-IDF framework source code. A code comparison shows ESP32-H2 is very similar to ESP32-C3 with a single RISC-V core, albeit clocked at up to 96 MHz, and the first Espressif SoC without WiFi, as the WiFi radio is replaced with an 802.15.4 radio for Thread, Zigbee, etc… that can be used for the development of Home Automation, Smart Lighting, and wireless sensor network applications. While looking at the source code differences between ESP32-C3 and ESP32-H2, the really only major differences were the 802.15.4 radio and lower maximum frequency, and at the current time, it looks like most of the rest is unchanged, so it’s possible they kept the same amount of RAM (400KB), storage, and most of the same peripherals, but it could just well be the code […]

$2 MXCHIP EMC3080 WiFi and Bluetooth LE IoT module integrates Cortex-M33 MCU

MXCHIP EMC3080 Cortex-M33 WiFi & Bluetooth-IoT module

While nowadays most people from the maker community are working with ESP8266 or ESP32 modules or boards for IoT projects requiring Bluetooth LE and/or WiFi connectivity, we’ve also covered some low-cost alternatives such as Bouffalo Labs BL602 or Realtek RTL8710. MXCHIP EMC3080 module offers yet an alternative with 2.4 GHz 802.11 b/g/n WiFi and Bluetooth LE 4.2/5.0. Where it differentiates against other solutions is that it features a more secure Cortex-M33 core clocked at 100 MHz, as found in UNISOC V5663 and Ameba RTL8722DM wireless SoCs, but still getting a fairly low price tag of $2.35 on Seeed Studio, which drops to $2.10 per pieces for orders of 10 or more units. MXCHIP EMC3080 module specifications: MCU – MX1300CF Cortex-M33 processor at up to 100 MHz with 256KB SRAM, 2MB XIP flash, 384 or 512 bytes OTP memory Connectivity WiFi 802.11 b/g/n 1T1R WiFi @ 2.4GHz Single Frequency HT20 support […]
