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 switch the radio module, not just limited to those two. Page views: 1588

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 client picks it up. When picked up, the client will light its LED for few…

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 slightly differs from what I last published, I did some more reshuffling, added a RESET…

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 single AAA battery. Alternatively,a CR2032 coin cell battery may be used. There is a socket for a…
