4x4 keypad with rf

Hello I have experience in designing electronics circuits and can make your project. I will make you project practically on breadboard and will provide you circuit, code and PCB design. I can also develop projects based on extra low power wireless SoCs. If you wish we can discuss in chat. Thanks

Hi there, we will fabricate the device using ARM cortex and silicon labs SI XXX . please feel free to contact us. Regards, Shahbaz.

Hi Sir, We can optimize it for your use, we can design with low battery consumption, we will study how long battery will lasts. We are professional engineers and developers who do such projects from the last eight years. We offer you our skills for this project at very low rates comparatively without compromising the quality of work. Let me introduce you to our company TURKTRONICS. We are TURKTRONICS. We are professionals with 8+ years of experience in Circuit designs, PCB designs, embedded system solutions, mobile app development, programming and software development. We provide complete end to end solutions for all kind of development projects. IOT is our strong point. In this bid, prototyping and shipping cost is not included however paying extra slight of money to include prototypes. We have collaboration with Atechcircuits & WELLS Inc in Shenzhen China for excillent quality PCB manufacturing. We care about our clients and help them to get out of any potential problem throughout the projects and also give post completion technical support if ever required. We are very much looking forward to hear from you on this in coming days! Cheers!!! Ahmad Lead Technical Engineer TURKTRONICS An Internet of Things Company !

Hi Sir, We have previous experiance with 4x4 matrix reading with efficient Bluetooth connection and Android App developments. Please contact us.

hello there, I have equipment to readily test your requirement. Please let me know what you plan to achieve and we can decide the way to go forward. Also please let me know the current design specifications so that I can fix and build upon faster for you. Merry Christmas!

I'm very interesting in your job. I always support "first time right design". Relevant Skills and Experience I have a high skill in pcb design, Cirsuit design, manufacturing. So i believe to assist you perfectly. I'd like to hear from you soon. Best Regards

Hello, I have already created a similar system using Si4455 and a Freescale Cortex M0+ chip. I can give you what you need..

hello sir/ma'am I have 4-year experience in PCB layout design(flex, multilayer). Its an easy task for me because I am working on Home Automation products from last 2 years All are Arduino based. I already develop some products which are using nrf24l01+ mini(for communication) amega328P(smd ) code on Arduino environment these are some examples 1. A modular Switchboard(slave) which takes data from a master hub(nrf24l01+mini communication) or remote(nrf24l01+mini communication) and control the home appliances, bulb and fans via atmega328. 2. THE REMOTE(MASTER) WHICH TAKES SIGNAL FORM 4x7 KEYBOARD AND SENT TO THE MODULAR SWITCHBOARD(NRF24L01+ MINI COMMUNICATION). THE REMOTE ALSO OPERATE TV AND AC BY IR COMMUNICATION. ALL PROCESS DONE BY ATMEGA328. IN POWER SIDE WE USE SMALL LI-ION BATTERY WHICH IS CAPABLE TO RUN THE REMOTE 50- 60 DAY( DEPENDS ON USE). PLEASE CHECK MY PORTFOLIO TO SEE ABOVE EXAMPLES IMAGE. skills PCB layout design CAD design embedded C power management custom boards barebone boards( low power consumption) communication (I2C, SPI, UART, Bluetooth, wifi) WE CAN DISCUSS IN DETAIL ON CALL(9479694124) OR OVER CHAT HERE OR ON WHATSAPP I CAN SAVE YOU MONEY TRANSFER AND SERVICE CHARGES.(IF HIRE BY TELEPHONIC CONVERSATION) IF HIRED I WILL EDIT YOUR DESIGN 3 TIMES IN SAME DEAL. foreign freelancer takes 3-4 hour for a reply.
