HiLetgo Single Board Computers 3-01-1033-B Editorial Review
Overall, customers found that the MT8870 DTMF Decoder module worked well and as advertised, with the exception of some customers receiving defective or open modules. Most customers used the module to control relays or decode DTMF commands in radio remote control systems, and noted that the outputs were 5V and needed an additional driver to increase the current for certain applications. There were no libraries or example code included or posted on the website, but customers found it easy to interface and program with an Arduino or Python. Some customers found the LEDs to be too bright, but this was easily solved by replacing or removing surface mount resistors.

“The prices—including shipping costs and customs duties—are clear from the very beginning, with no hidden fees. I highly recommend using their services. My experience with the "Ubuy" website was excellent. I purchased a PRS USA Swamp Ash Special guitar, and it arrived in just 11 days. The shipping service was fantastic, and the product arrived in perfect condition. What I particularly appreciated about the site is that the prices—including shipping costs and customs duties—are clear from the very beginning, with no hidden fees. I highly recommend using their services.”
