Beetle DFR0282

[AllenPitts]

Hello Sparkfun forum,

Using a single channel 433mhz transmitter/receiver to operate a payload release on a kite messenger. Had to use an Arduino sketch to get the receiver to send a travel menu to the servo.

Started design with a DFR0282 Beetle to send the menu to the servo

https://wiki.dfrobot.com/Beetle_SKU_DFR0282

because the Beetle is so small but cannot get the Beetle upload a sketch. So abandoned the Beetle and am looking for an Arduino sketch compatible component.

Have read the ‘Arduino Comparison Guide’ and it looks like Arduino Pro Mini 328 - 5V/16MHz will do the job.

It is understood that the Arduino Pro Mini 328 - 5V/16MHz does not have a USB connector so the

FTDI Basic Breakout board and the FTDI cable will have to be used to get to the Arduino IDE on the laptop.

But the range and array of Arduino compatible products:

SparkFun Qwiic Pro Micro

Arduno Pro Mini

Arduino Nano

Pro Miocro

Arduino Fio

is a bit over whelming.

Given the barebones needs of the project and a certain sensitivity to size and pricing,

since the microcontroller will be embedded in a product to be marketed, is the Pro Mini

seem like the best way to go?

Thanks.

That sounds a like a good choice for that mix - of those options it’s pretty small, and meets the specs

Hello TS Russell and the SparkFun forum,

Received the SparkFun FTDI Basic Breakout 5V and the Arduino Pro Mini 328 5V/16Mhz today. Did not realize the Micro USB connector was needed so the SparkFun Cerberus USB Cable - 6ft was ordered.

In the meantime working on a good way to connect the FTDI Breakout to the Pro Mini:

Just want to make sure the female headers on the bottom of the Pro Mini line up with the pads on FTDI Breakout line up as shown in the line drawing above.

Thanks.

Yep - just ensure you don’t slip it on upside-down
