Hello I am the owner of next Age cycles. I'm looking to have 3 custom pcbs made. The first one is for a brushless motor controller that will have many extra features and run about 200amp high voltage. Also need a BMS for a lithium ion. And I also need a display screen to go along with all of this and have them communicate with each other. More information upon request

Hello, We have a large team size and can give you resources in all departments from electronics to mechanical to software at a variable and low rate as per your requirement. We in house production capacity of more than 100k circuit boards per week and an assembly team of above 200 people, we can be your low cost production base in India which now happens to be cheaper than china in terms of production cost. We are a 14 year old Electronics design and Manufacturing Company working as an IOT design partner for Toshiba Semiconductors, Avnet, WPG and many others. Our past product experiences includes: - Communication products on (Bluetooth, wifi, gsm-2g/3g/4g with and without gps, Lora, sigfox) - commercial products (fully automatic top loading washing machine with fuzzy logic, smart microwave over, BLDC fans and compressor drives for air conditioners, Led lightings-home downlights, smart bulbs and tubelights, solar street lights and high bay lights) - Automotive products (tire pressure management systems, obd2, Bluetooth for infotainment, ev charging stations, BLDC drives, Battery management systems) - Retail automation (POS terminals and thermal printers) - Utilities (water flow meters and Energy Meters) We have a team of 40+ engineers in product design working in following domains: - Electronics hardware design - embedded software design on STM32/STM8/Toshiba TMpm series/MSP430/PIC 16 & 18/ Renessas RL78/atmega 16 and 32 series - Mechanical design on Autocad/catia/solidworks/ design pro. - Mechanical prototyping on 3d scanners and 3d printers - Application software developers on java / python / php / odoo-erp and android studio. We follow the agile work procedures with 15 day sprints and burn down charts communicated to the customers as well if needed. We have a production capacity to support international quality standards of production and packaging at a rate cheaper than china as we function in a tire 3 city of India. We can hence support mass production as well. We can also support with onsite training and support if and whenever needed. We hence requestfully submit our proposal for your evaluation and reassure you of our quality and promptness.

Hi I design Ebike electronics for other manufacturers as a freelancer. I have designed an ebike display that works with Bafang controllers. I have brought an ebike BMS to production, final stages. And I have a 3 phase motor controller under development. It is capable of a variety battery voltages from 17S down to 1S. The maximum current is dependent on the power stage components selected. From 300amps to 50amps. I plan to sell this controller for around $100 a piece but would make a large discount for unders over 50 units.

I'm a new freelancer in this platform and an elctronics engineer having BS and MS degree on electronics with many years of wide and extensive experience. I have designed hardware firmware and software for a servo system of stabilized platform for a yacht dish antenna with BLDC motors and an embedded actuation control unit-ACU- with raspberry pi. There is a GPS attached to the embedded system. The ACU have a GUI coded by QT. I have attached magnetic angle sensor to BLDC rotor. And it has 360/1024 = 0,35 degree precision. It is possible to increase the precision by decreasing step angle to 0,088deg. by the same magnetic angle sensor with additional work. ACU and BLDC controller can communicate via WiFi and CAN Bus. The attitude of dish can be seen on a graphical chart on embedded system in real time I have used Texas Instrument's a Piccolo micro-controller that has a floating point unit. For BLDC driver I have used TI's DRV8301. All PCBs are prepared with Altium designer. I can adopt this system for any speed and torque control too. By my this experience I think the development time will be very less for you. If you would like I can send a video belonging to the system.
