A presentation about Fuelino Proto2 is available here: Fuelino Proto2 Presentation. The slides above and below show the external connections pin-out of Fuelino Proto2. The board is capable to control 2 fuel injectors, through 2 FKI10531 MOSFETs. When closing the injectors, the voltage is clamped using 2 networks made by 4x 12V Zener diodes in … Continue reading "Fuelino Proto2 presentation"
To perform some tests, I interfaced the following modules to a Fuelino Proto2 board: Catalex MicroSD module, for data logging on micro SD card. Interfaced using SPI communication protocol (6-pin connector). LCD module (AE-AQM0802), for real time data visualization. Interfaced using I2C (TWI) protocol (4-pin connector). The picture below shows how the LCD display module looks … Continue reading "Data logging and LCD display visualization with Fuelino"
Recently, I had the necessity to power Fuelino with 12V voltage, but having only a PC with me. The purpose was to make some tests "on the desk": since recenctly I travel a lot, I don't have space to bring, with me, a complete "220V AC to 12V DC" power supply. So, I searched on Amazon … Continue reading "USB 5V to 12V voltage boost"
Some weeks ago, I received at home the second prototype of PCB for the Fuelino shield (compatible with Arduino Nano r3). Since all components are "through hole mount", and there are quite many, the soldering and testing phase required about 1 h. First of all, I decided to solder the resistors (they are the components … Continue reading "Fuelino proto2 PCB mounting"
