I already mentioned, that I have a small RFM12B ‘shield’ that can be used instead of the nRF24L01+ on a WorkerB!. I put one to a test today, all working as expected: This makes it easy to…
nRF24L01+ range testing
I did some range testing earlier today, using a ping-pong pair of sketches uploaded to a WorkerB! and a Dirt Cheap Low Power Wireless Sensor Node: This works by sending an incrementing value (millis’ value) every second, and the…
The WorkerB!
I have received 5 test PCBs today of the unnamed ‘ATMega32u4+nRF24L01’ board project that I described earlier, I decided to call it a ‘Worker Bee’ or WorkerB! as its task will be to collect and transmit data. The final PCB layout…
New ATMega32U4 board to use with nRF24L01
I laid out a new pcb design to eventually produce, it is a USB enabled ATMega32U4 @ 8Mhz/3.3V (same MCU as Arduino Leonardo) board with optional AAA battery holder on the back plus LC3525@3V boost regulator that will allow the thing to run off the…
nRF24L01+ power consumption footprint
I hooked my Dirt Cheap Low Power Wireless Sensor Node (DCLPWSN 🙂 ) to the scope to see what is going on during transmissions. I used this library for the test, and this code: /** * Pins: * Hardware SPI: *…
Dirt Cheap Low Power Wireless Sensor Node using nRF24L01+ 2.4GHz
I have mentioned before, that I have purchased couple nRF24L01+ units from eBay for the stunning $3 with delivery included. I decided to make some cheap tests this time, so went for a veroboard prototype. I got two blank DIP…
