Aconno Bluetooth 4.0 & 5 IoT Development Board Features an nRF52832 or nRF52840 Module, an e-Paper Display, Sensors and More

Bluetooth 5 is the latest iteration of Bluetooth with up to four times the speed and twice the range of Bluetooth 4.0 LE, and so far apart from Puck.js and Nordic Semi nRF52840 devkit, I had not seen many Bluetooth 5 IoT modules or boards. Aconno, a German startup, has designed ACD-52832 Bluetooth 4.0 / Thread / ANT+ IoT development board based on their own nRF52832 module, and equipped with some goodies like a black & white e-Paper display, a joystick, sensors, I/Os, etc… They’ve also launched an updated module with Bluetooth 5 using nFR52840 SoC. I don’t have the full details about the new module, but the nRF52832 module and devkit is interesting to look at, especially features should be similar. Aconno ACD-52832 board specifications: Wireless Module – ACN52832 based on Nordic Semi nRF52832 ARM Cortex-M4 @ 64 MHz SoC with Bluetooth Smart, ANT+, Thread, NFC, and 2.4 GHz […]

$2 Wisol SFM10R1 & SFM10R2 Sigfox Modules and Evaluation Board

LoRa appears to be one of the most popular long range lower power WAN standards, at least based on the number of hobbyist boards coming to market, but hardware is not exactly cheap with modules such as Microchip RN2483 & RN2903 LoRa modules selling a little over $10, and development board such as LoPy normally going for at least $35. If large scale IoT is ever going to take off, prices will have to go lower, and AFAIK we are still waiting for the promised sub $2 Weightless chips. But if Elettronica In tweet is to be believed some Sigfox modules made by Korean company Wisol are selling for just $2, likely in larger quantities. WiSOL SFM10R1 is made with RCZ1 (Radio Configuration Zone 1 – ETSI – Europe), while SFM10R2 module is made for RCZ2 ((Radio Configuration Zone 2 – FCC – North America). SFM10R1 key features and specifications: […]
