Hey guys
First of all sorry for my poor english, i hope evereybody understand what a mean/want.
I´m Patrick from Austria and I study elektonic
I dont like the current remote solutions like Wiiceiver or a car remote because they are not made for a Eboard!
Thats the reason why i designed a new remote with a bidirecitonal comunication that includes a BMS during the last week.
Now I want ideas form you to improve it.
This is a first version, there are maybe faults in it.
what extras/gimmicks do you want?
The whole stuff is designed to work with a standard ESC or a VESC
standard ESC: PWM output
VESC: connection through I2C or USART
REMOTE
Nunchuck Design
3D printed
18650 cell powersource (USB recharable)
NRF24L01+ transceiver
2 axis Joystick (only one axis in use)
128x128 pixel Display
Cruise controll Button
2 buttons and an incremental encoder for the HMI
Tech Spec:
Controller: Atmega328
Display: LS013B7DH03 Sharp
Joystick: same as in the Nunchuck
USB Charger: MCP73831
REVEIVER / BMS / BEC
90x50x15mm
2 stacked PCBs
- one with the Receiver, BEC and Switches
- one with the BMS
3 Switches (max 3A) for Front/Rear ligth and an extra channel (PWM)
Receiver:
Controller: Atmega328
NRF24L01+ as receiver
BMS:
LTC6803 (supports LIFEPO4 Cells)
Aktive Balancing
with his own small Controller
Always ON/Standby and self powered from the Battery
BEC
5V/3A by LM2576HV (Controller and Front/Rear lights)
3.3V/100mA (for the NRF24l01+)
PICS
estimated Price for one unit:
Remote Case: 30€
Remote Hardware: 30€ (display 17€)
BEC:12€
RX: 10€
BMS: 35€
if we order more, its getting cheaper
What´s your opinion? What is good / bad / to improve?
