Here’s Hermione with her new PCB. It’s passed the passive tests; next step is to make sure each of the 8 motor ESCs are connected the right way to the respective PWM output on the PCB, and finally, I’ll do a quick flight with only the MPU-9250 as the sensors to tune the X8 PID gains. Then she’s getting shelved.
Zoe’s getting a new PCB so I can run the camera and Garmin LiDAR-Lite V3 on her too. Hermione is huge compared to Zoe, and with the winter weather setting in, I’m going to need a system that’s small enough to test indoors.
Hermione will still be built – I need her extra size to incorporate the Scance Sweep and GPS, but I suspect only when an A3 arrives on the market – Hermione’s processing with a new 512MB A+ overclocked to 1GHz is nearly maxed out with the camera and diagnostics. She’s probably just about got CPU space for the compass and Garmin LiDAR lite over I2C but I think that’s it until the A3 comes to market. My hope for the A3 is that it uses the same 4 core CPU as the B2 with built in Bluetooth and WiFi as per the B3 but no USB / ethernet hub to save power. Fingers crossed.
