WebJan 23, 2013 · ULN2803. We looked at the L293D in Lesson 9. The ULN2803 is a very useful chip. Whereas the L293D effectively has four outputs whose polarity can be reversed, the ULN2803 has eight outputs that amplify the weak signals from the raspberry Pi GPIO pins allowing them to switch much higher currents. However, unlike the L293D … WebDec 15, 2024 · The Pi's chip doesn't have a fully-baked PCIe bus. It's perfectly adequate for USB 3.0 chips (like the VL805 used in the Pi 4 model B and Pi 400), most NVMe SSDs, and a number of other devices, but the Pi locks up in strange ways when you try something crazy like plugging in an AMD Radeon RX 6700 XT.
