The SWD connection of the nRF52832 is accessible via the USB data lines in the USB Connector. The best is to use a Female USB connector to pass power to the PCB and connect to an St-Link at that pointTo add the Triink to Arduino it is best to use this...
Let's go through the main components of Torrus ! First the brain, an nRF52832 bluetooth 4 (and BLE 5 enabled) chip with a ARM Cortex M4. It can run quite some badass algorithms, supports encryption, has NFC, and on top of that is pretty famous in...
NRF52832 Contains an internal temperature sensor with 0.25 °Celcius Resolution. it can measure the die temperature over the temperature range of the device. Linearity compensation can be implemented if required by the application. Main Features...
A stripped down version of LPS^2 Mini (no UWB) will be sent to the factory on Monday. Main features: * Cortex M4F (nRF52832).* BLE, ANT or your favourite home made ISM protocol for 2.4 GHz.* Accelerometer, gyro and magnetometer: MPU-9250.* Altimeter/barometer:...
Features:* Flip dot display 7x7 pixels.* Has Bluetooth 5 for connecting to phones (Nordic nRF52832) (Nordic Bluetooth UART).* Uses 24V power supply (because display module needs that much).* Has 2 tact switches (haven't decided their functionality yet).*...
...everything looks like a nail. I put some thought into what controller I should use for the watch, and what it should display. My initial idea was to use an AtTiny chip. Then, I though that an AVR might give me a bit more flexibility,...
For instructions on actually programming the device, see the project GitHub repository README: https://github.com/curtpw/nRF5x-device-reverse-engineering and videos from this project which also involves hacking Nordic nRF52832 MCU based fitness...
My goal was for the electronics portion of the bracelet to be small - like 10 x 20 mm.... unfortunately, the haptic motor requirements mean that I need a larger battery - making my design - best case - 15mm x 35mm. Given that, I'm rethinking...
I have ported zeptoforth to the nRF52840, based on my port to the nRF52832, which turned out to be extremely similar to it. Unfortunately, I have been unable to run the nRF52840 port on the nRF52840-DONGLE board I now own, because the nRF52840-DONGLE...
Main components: - Bluetooth 4.0 module based on CC2541/2540 chip (HM-10), - any raindrop sensor, - few manipulators (actuators), - Nordic nRF52840 bluetooth 4.0 LE module. The toolchain: MinGW, GNU-ARM-GCC, Black Magic Probe (BMP)...
When you want to measure the temperature of the surroundings while developing Bluetooth low-energy projects you require an external temperature sensor. implementing external sensors increases the BOM Cost and requires a bit more space. you can avoid...
[full walk through video coming soon] HACKING THE B20 FITNESS TRACKER'S nRF52832 ARM CORTEX MCU AND ACCESSING ADS1292 BIOIMPEDENCE DATA Hacking the fitness tracker is very simple, all you have to do is solder wires to four (V+, GND, clock, data) big...
I have created a simple font for the X9 OLED display and used it to demonstrate text communication over serial Bluetooth using my Android phone. The BLE_CHAT example will display input from the Nordic phone app on the X9 display. If "red", "blue", "green",...
The hardware identified so far is the following: - nRF52832 chip - Color Memory LCD (panel by JDI, most likely) with backlight, using ST7301 controller - One touch button (handled by 233DH IC) - Vibration motor - BMA253 tri-axis accelerometer - Heart-rate...
So recently I've been focused on BicycleCompanion, which I also submitted to HackadayPrize, since as I mentioned in last log I hit a bump with current design based on NRF51822. I still have no idea why I couldn't get Bluetooth to work but having...
