Pettee Manufacturing has launched an ultra-wideband positioning board, constructed round Decawave’s DWM1000 transceiver and an STMicro STM32F4 microcontroller: the Pettee UWB Board.
“The Pettee Extremely-Wideband (UWB) board makes use of an STM32F401RBT6 microcontroller making it quick and permitting it to run highly effective purposes,” the corporate writes of its design. “It’s totally suitable with the Arduino IDE utilizing the Pettee UWB customized board definition which incorporates instance sketches that exhibit performance for all the built-in peripherals of the board. Moreover, this board is totally suitable with STM32CubeIDE, ProjectIO (Visible Studio Code), and another IDE that helps flashing STM32 MCU based mostly boards.”

Not like rivals, the Pettee UWB Board is being offered as a ready-to-run package: Along with the event board itself, the corporate is bundling a 3.7V 1.2Ah lithium-ion battery and a PLA enclosure for cover. Charging is dealt with by a built-in battery administration system, with help for wi-fi charging.
The bonus options do not cease there: The corporate has additionally included a six-axis inertial measurement unit (IMU), a buzzer/vibrator module for haptic suggestions, two user-addressable single-color LEDs in pink and inexperienced respectively, and quick access to the microcontroller’s I2C, USART, and JTAG ports.
Pettee claims a four-inch positioning accuracy, however that is solely achievable utilizing a number of boards: A single board in “tag” mode mixed with three “anchors.” The microcontroller, in the meantime, runs at 84MHz and affords 64kB of RAM and 128kB of program storage — however you will want to select up a Serial Wire Debug (SWD) programmer, such because the ST-Hyperlink V2, to get it operating your code.

The Pettee UWB is not the primary ultra-wideband positioning board we have seen of late: On the tail finish of final yr Makerfabs introduced its personal UWB positioning module, constructed round an Espressif ESP32 microcontroller and providing the identical claimed four-inch accuracy. Just like the Pettee, it is based mostly across the Decawave DWM1000 transceiver — however lacks the Pettee’s six-axis IMU, battery administration system, wi-fi energy help, and buzzer/vibrator.
The Pettee UWB Board bundle is now out there to buy on the corporate’s Tindie retailer at $69.99; supply code is because of be revealed to GitHub underneath the reciprocal GNU Normal Public License 3, however on the time of writing had not but been uploaded.
