Indoor positioning BU01 development board can detect tiny body movements (Sponsored)

GPS is available for outdoor positioning, what about indoors? There is a positioning technology that is more accurate than GPS: UWB. The technology offers positioning accuracy within 10cm which greatly compensates for the shortcomings of the indoor RSSI positioning of past IoT products. UWB technology is a wireless carrier communication technology that uses a frequency bandwidth above 1 GHz. It does not use a sinusoidal carrier but uses nanosecond-level non-sinusoidal narrow pulses to transmit data and occupies a large frequency spectrum, hence the name “Ultra-Wideband”, or UWB for shorts. Besides positioning, UWB can also be used for data transmission with a rate of hundreds of megabits per second. BU01 development board features MCU – STMicro STM32F103 Arm Cortex-M3 microcontroller UWB module – Ai-Thinker BU01 module 50 I/O pins exposed for functions. Sensors – Onboard acceleration sensor, temperature, and humidity sensor Misc – User buttons and LED Power Supply – 5V […]

Blues Wireless Swan board adds castellated holes to Adafruit Feather form factor

We’ve often written about Adafruit Feather-compatible boards in the past, but Blues Wireless Swan board is a little different, as the STM32L4-based board comes with castellated holes instead of just through holes which allows the board to expose up to 55 GPIOs, or 36 more pins than a traditional feather-compatible board. The company also introduced the “Feather Starter Kit for Swan” that enables the board to work with the company’s Notecard LTE Cat-M/NB-IoT M.2 modem that ships with 10-year (up to 500MB) of IoT connectivity, as well as GPS/GNSS connectivity. The Swan board Swan specifications: MCU – STMicro STM32L4R5 Arm Cortex-M4 microcontroller clocked at 120Mhz with 2MB of flash and 640KB of RAM USB – 1x Micro USB port for power and programming Castellated holes giving access to 55 GPIO including: 8x analog input 16x digital 4x I2C, 3x SPI 1x USB OTG full speed 1x 14-channel DMA 12-bit ADC, […]
