Amazon LEDS (8$/5 pack) with Dupont wires are for 12 Volts, way above RPi (may be they work for 3v3...)
Another solution (10$/25 pack) would be to use LEDs where the resistor is inside but no soldering to Dupont wires : wrapping is not that difficult - https://www.sparkfun.com/products/14563 resistor is prewired, but not Dupont wires (are expensive and can break easily)
Ther is another solution : use solderable broad beards , or even, RPi dedicated solderable boards: https://hackspark.fr/fr/outils-de-dev/1 ... board.html That remains small, and is very easy to plug/unplug (if you need "many LEDs, unplugging them is error prone and boring, more than soldering/verifying). Broad beards are a mixture of disadvantages: Dupont wires, more fragile than soldering
I found another way , with screws https://hackspark.fr/fr/electronique/66 ... ry-pi.html but it seems discontinued and has "only" 26 pins (modern RPi have 40 pins).... It already has/had two Leds: one power and one to be connected to pin 25 (no choice) -it is/was very expensive, however-)
Edited a google serch wit "rpi prototyping board" led me to a 40 pin GPIO, each and every one is connected to screws : https://jeulin.com/jeulin_fr/277006.htm ... 5sQAvD_BwE
This is 17$, perhaps... more expensive than a RPI zero...
This is less expensive than https://thepihut.com/products/gpio-term ... indicators (has LEDS on each and every pin of the GPIO; if one is unhappy with presoldered LEDS, has screws to put other LEDS.....)
