Problem with 2.00 to 2.54 dupontcable is that on the 2.00 side they’re by two and measure 4.29mm so you can’t fit four of them to cover all the 8 pins. But it’s ok if you don’t need all the pins on a given side. ---

I soldered a 2.54 mm header with long pins bending them with a plier before to adjust to 2.00 mm spaces. The long pins fit well in breadboards and dupont cables. ![](https://www.thethingsnetwork.org/forum/uploads/default/original/2X/c/cb5fda7c2c0e784c1f01ffe06136c77764e31604.jpg) ---

Shipping is from Taiwan so free shipping is probably not restricted to US only. You can click the link and check it yourself. ---

Another option for Arduino UNO (and compatibles) is this special dual-pitch prototyping PCB shield: > [@The BARGAIN basement part 4](https://www.thethingsnetwork.org/forum/t/the-bargain-basement-part-4/13560/116): > > Dual-pitch prototyping PCB shield for Arduino Uno (and compatibles) [[54mm%20Pitch%20Prototype%20PCB%20for%20Arduino%20UNO]](https://www.aliexpress.com/item/Combo-2mm-2-54mm-Pitch-Prototype-PCB-for-ArduinoUNO-R3-Shield-Board-DIY-bte16-07-15MM/32673829711.html) Can be used for adding LoRa modules with 2mm pitch (RFM95W, SX1276, HPD13A) and components with regular 2.54mm pitch (OLED display, sensors, buttons, etc.).

Adding multiple paths to the antenna pad like here (SMA, header pin, wire hole) is not good and none of these paths is shielded. Each path will act like a small antenna. This results in impedance mismatch and (possibly major) RF losses. ---

Cutting the tracks leading to unused options close to the mounting pad should help but otherwise agree 😉 [Next page](https://www.thethingsnetwork.org/forum/t/making-rfm95-breadboard-friendly/8248.md?page=2)
