$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 […]

Pico 2G Expansion adds GSM/GPRS & GNSS to Raspberry Pi Pico (Crowdfunding)

You may have heard about the 2G/3G sunset with the older cellular networks being phased out in many countries. But it’s not always straightforward, as telecom operators may have to obtain regulators’ permission for the shutdown notably because of the eCall emergency services integrated into cars in Europe. Eventually, eCall will be migrated toward IMS Voice and 2G M2M services to 4G LTE IoT and 5G LPWA, but in the meantime, 2G networks are still operating in parts of the world, and UK-based SB Components has just introduced the Pico 2G Expansion board for Raspberry Pi Pico based on the SIM868 module. Raspberry Pi Pico 2G Expansion specifications: Compatible with Raspberry Pi Pico board Display – 1.14-inch LCD Cellular & GNSS Connectivity SIM868 module with GPRS multi-slot class 12/10, mobile station class B GSM 850/900/1800/1900 MHz GNSS – GPS/GLONASS/BDS Bluetooth 3.0 with audio support SIM card holder 2x SMA antenna […]

Posture correction smart sensor helps you sit or stand upright

It’s easy to adopt a bad posture either while sitting in front of a computer or while walking and your mobile, and over time this may lead to unaesthetic and/or painful postural disorders. To solve this issue, a posture correction smart sensor may be used in place of a posture belt with what looks like a GPS tracker placed on the back of the patient, and which notifies bad postures by vibrating and to your smartphone depending on a user-configured angle range. Specifications listed for the posture-correction-smart-sensor: Sensor – Unnamed Bosch gravity sensor Connectivity – Bluetooth 4.2 Misc Medical-grade gel patch to attach the device to the bag Vibration motor Battery – 200mAh; 30 minutes charge good for about 5 days when using it for about 8 hours per day Dimensions – 6 x 4 x 1.2 cm Weight – 16 grams. The device ships with a micro USB cable […]

InfiniTime 1.0 firmware released for PineTime smartwatch

The PineTime smartwatch was unveiled and first launched in 2019, as a low-cost, open-source wearables development kit/platform for developers wanting to work on firmware development for the Nordic nRF52 powered device. Progress was made on various solutions such as ATCwatch Arduino firmware, and as time passed, the PineTime slowly became more like an “enthusiast-grade” end-user product. This is basically what it has become with the first stable release of InfiniTime firmware, which was selected as the default firmware in September 2020. The main features of InfiniTime 1.0 firmware include: Two clock faces – digital and analog Apps – Stopwatch, music control, navigation, heart rate, as well as Paddle and 2048 games User settings – Display timeout, time format, wake up conditions OTA upgrades via an open-source bootloader based on MCUBoot Heart rate monitoring and step counting Between 3 and 5 days of battery life depending on usage Firmware based on […]
