Review: Does the job - Feels funky to use at times, feels extremely cheap for the price but gets the job done.
Review: Useful for converting Serial to Bluetooth - For both hobbies and professionally I work with Serial UART devices, and it's useful to be able to convert those signals to Bluetooth. The HC-05 uses Bluetooth 2.0 (an old standard), but that's all that's needed for achieving serial over Bluetooth, and the protocol is backwards compatible. You'll find plenty of libraries that work with this so you can easily connect Arduino, ESP32, and other chipsets serial UART to a PC or Android phone over Bluetooth. As for packaging, the PCB just came in a no frills bubble wrapped anti-static package. I gave this a quick test with a STM32 and was able to get it to connect on my Android device to a flutter application without a problem. Overall I recommend this product if you need to convert a serial UART to Bluetooth. It's easy to work with, it's been around a long time, and the cost is low.

### ⭐⭐⭐⭐ Does the job

### ⭐⭐⭐⭐ Classic Bluetooth Serial module
*by J***N on July 13, 2025*

The design and PCB setup of this HC-05 Bluetooth UART module has been around for a very long time. It's the much older Bluetooth 2.0 Classic protocol. For comparison, the newest Bluetooth version that's on modern phones is Bluetooth 5.0--which luckily still has some backwards compatibility with Bluetooth 2.0 on mobile devices. Part of being around for so long is there are a lot of libraries to interface with this and you can easily find Arduino code to set this up. I haven't been able to get this to connect with iPhones/iPads due to their restrictions on the Bluetooth stack, but it works fine with Android and PCs after getting the Bluetooth libraries installed to interface with the bluetooth serial. Useful for remote debugging with just my Android phone.
