![]() I know it is necessary on the NRF24, but it is not clear in the instructions if this is the case on RFM69. It has no usb port so how can it be programmed Edit: I have discovered that there is a new device called 'Arduino Pro Micro' which is similar to Pro Mini and Nano but have usb port in-built. I have got an Arduino Nano working with NRF24 with several nodes, but since I only have five NRF24 modules and maybe 30 RFM69 modules (and thick concrete walls in a big house) my goal is to use RFM69 (433 MHz).Īlso - is a capacitor necessary on the RFM69 module? Fritzing diagram showing the connection between a USB to UART bridge and a Pro Mini 6 pin SIL, 0. Our boards have silkscreen labels of where the black and green wires of the FTDI TTL-232R cables would be. I understand that the 8 MHz may be insufficient for a gateway with many nodes in the long run, but this is just a short term test to achieve at least some kind of success with the RFM69 module, which has so far been the cause of many headaches. diymore FT232RL FT232 FTDI USB 3.3V 5.5V to TTL Serial Adapter Module Mini USB Port for arduino pro mini USB TO 232 USB to TTL. We often use right angle headers on the Arduino Pro Mini to make connecting a serial bridge trivial. My goal is to have an Arduino Uno (5V) as a serial gateway, but since I don't succeed with that in spite of logic level converters on the MOSI, SCK and NSS, I wanted to try and get it working on a 3.3V Pro Mini so the logic level conversion complexity disappears. In the code it states: * The GW code is designed for Arduino Nano 328p / 16MHz Will serial gateway work with 3.3 V Arduino Pro Mini (8 MHz)? How to program an Arduino pro mini using native serial port (on my mainboard) Ask Question Asked 4 years, 4 months ago Modified 3 years, 3 months ago Viewed 735 times 0 How can I program my Pro Mini using the native RS232 Serial port on my Mainboard (aka com1).
