Tegg Access-Control Keypads Editorial Review
Tegg 1PC 3x4 Keypad MCU Board The Tegg 1PC 3x4 Keypad MCU Board is a small and cheap keypad that is advertised for use with Arduino and Raspberry Pi. However, customer feedback regarding this product has been mixed. Some customers have found that the durability of the keypad is satisfactory. They mentioned that the keys functioned correctly when connected to their Arduino boards. However, there were concerns about the high resistances on some of the keys, which could potentially cause issues in certain circuits. On the other hand, other customers have expressed dissatisfaction with the build quality of the product. They reported that the solder points were poor, making it difficult for solder to stick to them. Additionally, there were complaints about the plastic not being properly melted, resulting in the keypad not staying closed. Some customers even encountered shorts between the columns and rows. Furthermore, there were comments about the pinout not being standard or documented, which could cause confusion for users. The solder mask was said to burn easily, and some pads came already lifted. These issues contributed to the perception of the product being unreliable and of low quality. In summary, the Tegg 1PC 3x4 Keypad MCU Board has received mixed reviews from customers. While some have found it to be durable and functional, others have experienced problems with the build quality and reliability of the product.
