Some suppliers the ground pins are on the right and other suppliers the ground pins are on the left side. ### ⭐ Ware ist falsch - keine Möglichkeit der Reklamation nach Ablauf der Rückgabefrist. *by S***L on Reviewed in Germany on 25 May 2023* Habe vor einiger Zeit 2×3 Stück dieser Module gekauft. Die Rückgabefrist endete im April. Jetzt, wo ich die Teile nutzen will stelle ich fest, dass es nicht möglich ist ein Programm über Rx/Tx auf das Modul zu bringen. Nach langem probieren habe ich über ISP ein Programm draufgebraucht. Ein einfaches Blinkprogramm, das aber statt im 5s Rythmus im 2,5s Rythmus arbeitet. Also hat das Modul, statt 8MHz 16MHz. Die Spannung stimmt mit 3,3V, was eigentlich nicht spezifiziert ist. Ich kann die Teile also nicht gebrauchen. Einen Kontakt läßt sich über Amazon aber nach Ablauf der Rückgabefrist nicht mehr herstellen. Eigentlich gilt in Deutschland 2 Jahre Garantie. Und nun? Bleibe ich auf dem Schaden sitzen? ### ⭐⭐⭐⭐ Pretty happy *by A***N on Reviewed in Australia on 24 October 2020* Got these to use USB host boards that were designed to go on them. The supplied faulty USB host boards didn't work at all but these little Pro Mini boards are actually pretty good. All the power of an Arduino UNO (with 2 more analog pins) in a tiny package without the space wasting programming circuitry permanently built in. I recommend getting some for the box. I won't even be bothering with Arduino NANO boards anymore. These are smaller and delivered in very reasonable time. ## Frequently Bought Together - HiLetgo 3pcs Pro Mini ATmega328P 3.3V 8M Module Board with Crystal Oscillator Compatible Arduino Pro Mini Replace ATmega128 - HiLetgo 4pcs NRF24L01+ Wireless Transceiver Module2.4G Wireless Transceiver Module - Chanzon SMD Fast Switching/Schottky/Rectifier Diode Assorted Kit (15 Values Total 150pcs: M1 M4 M7 S1M S2M S3M SS14 SS16 SS24 SS26 SS34 SS36 RS1M US1M LL4148) Electronic Component Assortment Set --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/424097077-3pcs-pro-mini-atmega328p-3-3v-8m-module-board-crystal](https://www.desertcart.co.uk/products/424097077-3pcs-pro-mini-atmega328p-3-3v-8m-module-board-crystal) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-16*
