Enhanced data rate (EDR) conforms to the 2Mbps and 3Mbps modulation modes of the V2.0.E.2 specification. Full speed Bluetooth , support for full Piconet and Scatternet. On-board 3.3V regulator chip, ROHS compliant, compact size. Spec:Bluetooth software stack, you can use this Bluetooth module with your system:* For MCU, ARM or For system.* For SOC system.* Digital Assistant (PDA)* Computer Accessories* Other systems you want to use under Bluetooth.UART interface and baud rate setting functionSupport on-board 8Mbit external flash memorySupport for 802.11Co-ExistenceHardware:CSR solution, Bluetooth V2.0 protocolSupport AT CommanderSupport Master and Slave modes, modified by AT Commander.Support 1200-115200 baud rate.Power: 3.3V single power supplyCore module size: 28 * 15 * 2.35mm/ 1.10 * 0.59 * 0.09inOverall module size: 35.33 * 19.6 * 3.7mm/ 1.39 * 0.77 * 0.14inPackage Include:1 * Bluetooth Module 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. ## Features - Enhanced data rate (EDR) conforms to the 2Mbps and 3Mbps modulation modes of the V2.0.E.2 specification. - Full speed Bluetooth , support for full Piconet and Scatternet. - Support Bluetooth connection through AT command, set baud rate, password, save parameters after setting parameters. - On-board 3.3V regulator chip, ROHS compliant, compact size. - Bluetooth UART RS232 serial converter module for easy transfer of UART data. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08Z3J9Y8T | | Best Sellers Rank | #73 in Serial Port Cards | | Customer Reviews | 3.9 3.9 out of 5 stars (12) | | Date First Available | March 16, 2021 | | Item Weight | 0.176 ounces | | Item model number | Cuifatizviyfx8bgn | | Manufacturer | Cuifati | | Product Dimensions | 0.39 x 0.39 x 0.39 inches | ## Product Details - **Brand:** Cuifati - **Compatible Devices:** Laptop, Desktop, Smartphone, Tablet, Other Computing Devices - **Data Link Protocol:** Bluetooth - **Data Transfer Rate:** 3 Megabits Per Second - **Hardware Interface:** Bluetooth - **Item Weight:** 5 Grams - **Manufacturer:** Cuifati - **Product Dimensions:** 1.39"L x 0.77"W x 0.15"H ## Images ![Bluetooth Module UART RS232 Serial Converter HC-05 Transceiver Module Serial Port Communication BT Module - Image 1](https://m.media-amazon.com/images/I/61bBNUel7GL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐ Does the job *by D***Z on May 26, 2025* Feels funky to use at times, feels extremely cheap for the price but gets the job done. ### ⭐⭐⭐⭐ Useful for converting Serial to Bluetooth *by H***N on October 28, 2025* For both hobbies and professionally I work with Serial UART devices, and it's useful to be able to convert those signals to Bluetooth.

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. ## Frequently Bought Together - Bluetooth Module UART RS232 Serial Converter HC-05 Transceiver Module Serial Port Communication BT Module - 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 - BOJACK L298N Motor DC Dual H-Bridge Motor Driver Controller Board Module Stepper for Arduino Intelligent Car Power UNO MEGA R3 Mega2560 with 4pcs --- ## 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.in/products/470463985-bluetooth-module-uart-rs232-serial-converter-hc-05-transceiver-module](https://www.desertcart.in/products/470463985-bluetooth-module-uart-rs232-serial-converter-hc-05-transceiver-module) --- *Product available on Desertcart India* *Store origin: IN* *Last updated: 2026-05-21*
