This board is a Perfect Companion to the Arduino Family of Micro Processors, and Easily Connects. Allowing one to use their Smartphone to Communicate and Control their Processor of choice. I had No Difficulty in getting the device to work, and although you can change the "Default" Settings, I found that they were suitable for my projects. I am using this particular unit with an Arduino Nano in an "Otto" Robot that I have assembled. And I am using my Cellphone to send commands to My Otto Robot, that really increased the function. The HC-06 Device was Delivered in an AntiStatic Bag and was carefully packaged for shipping. The unit arrived in Brand New Condition without any damage or bent Pins. I was more than pleasantly surprised at the Quality of the Product and the build of the Circuit Board and Attachment of the Chips. A few Connections and the Board Powered up with the Indicating LED's giving firm indication of Operation. DSD Tech did a fine job in delivery and shipping. And the Product was "As" Described. I will Buy Again from them. ## Frequently Bought Together - DSD TECH HC-05 Bluetooth Serial Pass-through Module Wireless Serial Communication with Button for Arduino - 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 - HiLetgo 3pcs GY-521 MPU-6050 MPU6050 3 Axis Accelerometer Gyroscope Module 6 DOF 6-axis Accelerometer Gyroscope Sensor Module 16 Bit AD Converter Data Output IIC I2C for Arduino --- ## 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.co/products/254082137-dsd-tech-hc-05-bluetooth-serial-pass-through-module-wireless](https://www.desertcart.co/products/254082137-dsd-tech-hc-05-bluetooth-serial-pass-through-module-wireless) --- *Product available on Desertcart Colombia* *Store origin: CO* *Last updated: 2026-05-26*
