Review: Good product but no documentation - Probably a lot of one-star reviews would not have been posted if the seller had provided the keypad pinout. With reference to the attached photo, the R and C (row and column) lines are: BLK - R2 ORA - R3 GRN - C3 YEL - R4 RED - C1 BLU - R1 WHT - C2 I had no issues soldering the header. Fine tip is definitely recommended. Review: No wiring information, Matrix for keys not properly set up, No leads to solder on - I bought this for a home automation project that needed a basic 3 x 4 number pad for user inputs. The style of the product is what sold me on it. I was okay with soldering on my own wire but due to the design of the product it became tedious and I almost melted the plastic on the housing due to the iron being to close. Even after getting it all solder together I was still willing to try to salvage the device. When I got to actually programming the device however, I was unable to determine the proper pinout since there is none given. After trial and error of picking pins and pushing buttons I determined that the device is not worth the effort. This product should come with some kind of pinout and to be able to solder from the other side of the board so you don't damage the plastic. ## Features - High Quality 12 Button Tactile Keypad .

The letters are slightly engraved into the plastic, so remov8ng just those would be hard as well. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good product but no documentation *by W***Y on December 28, 2024* Probably a lot of one-star reviews would not have been posted if the seller had provided the keypad pinout.

Decoding with a VOM showed that pins 1-3-5 were columns, pins 2-4-6-7 are rows. Resistance of keyswitches is several hundred ohms on the unit tested. All in all, no complaints so far. ## Frequently Bought Together - Tegg 3x4 MCU Board Matrix Array Switch Tactile Keypad - 12 Button Phone-Style Matrix for Arduino Raspberry Pi - GeeekPi 2-Pack I2C 1602 LCD Display Module 16X2 Character Serial Blue Backlight LCD Module for Raspberry Pi Arduino STM32 DIY Maker Project Nanopi BPI Tinker board Electrical IoT Internet of Things - ELEGOO 120pcs Multicolored Dupont Wire 40pin Male to Female, 40pin Male to Male, 40pin Female to Female Breadboard Jumper Ribbon Cables Kit Compatible with Arduino Projects --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.my/products/147575298-3x4-mcu-board-matrix-array-switch-tactile-keypad-12-button](https://www.desertcart.com.my/products/147575298-3x4-mcu-board-matrix-array-switch-tactile-keypad-12-button) --- *Product available on Desertcart Malaysia* *Store origin: MY* *Last updated: 2026-05-18*
