Today I found in a drawer of my old lab this board, and memory began to go into the past. Was 1996 , 16 years ago this is my first board based on a 16 bit micro controller that used 'C' firmware that i called VR1000 (see on the bottom layer) .
I developed that board for a BUS Fleet Managment application .
That board was based on Siemens 80c166 in future that was the base for ST 10 a father of STM32.
The specification of this board was :
With this kind of board was possible to fly a drone 16 years ago but the main problem was the sensor
In this sensor is possible to see the VR1000 (1996) and VR Brain MP32F4 IMU (2012)
80c166 (16 bit micro controller)
VR BRAIN MP32F4
STM32F4 (32 bit micro controller)
VR1000 RAM and PROM
64 Kbyte EEPROM and 32 Kbyte Ram (external)
VR BRAIN MP32F4 RAM and PROM
1 Mbyte Flash and 192 Kbyte Ram
VR1000 vs VR MP32F4 speed of processor
20 mhz vs 168 mhz
Advanced feature available only in MP32F4 :
Internal FPU - DSP floating point processor.
MPU6000 3 gyro 3 acc
I am very curious to know how will the new micro controllers for DIY applications in 2028 :)
