It seems every day there’s a new microcontroller announcement for which the manufacturer is keen to secure your eyeballs. Today it’s the turn of Espressif, whose new part is the ESP32-P4, which despite being another confusingly named ESP32, is a high-performance addition to their RISC-V line-up.
On board are dual-core 400 MHz and a single-core low power 40 MHz RISC-V processors, and an impressive array of hardware peripherals including display and camera interfaces and a hardware JPEG codec alongside the ones you’d expect from an ESP32 part. It’s got a whopping 768 KB of on-chip SRAM as well as 8 K of very fast cache RAM for intensive operations.
So after the blurb, what’s in it for us? It’s inevitable that the RISC-V parts will over time displace the Tensilica parts over time, so we’ll be seeing more on this processor in upcoming Hackaday projects. We expect in particular for this one to be seized upon by badge developers, who are intent on pushing extra functionality out of their parts.So we look forward to seeing the inevitable modules with this chip on board, and putting them through their paces.
Thanks [Renze] for the tip.
What if a socket on your phone or laptop fails? First off, it could be due to dust or debris. There’s swabs you can buy to clean a USB-C connector; perhaps adding some isopropyl alcohol or other cleaning-suitable liquids, you can get to a “good enough” state. You can also reflow pins on your connector, equipped with hot air or a sharp soldering iron tip, as well as some flux – when it comes to mechanical failures, this tends to remedy them, even for a short period of time.
