- cranberryturkey 3y agoso who's stock should i buy here??
- stevenhuang 3y agoThe one I linked is a good starter, it's by the manufacturer and has the programmer, dev board, and extra chips. They have other listings too of other variants, such as one with PHY for ethernet connectivity and much more GPIO and compute.
- Lord_Zero 3y agoWhat is special about RISC-V? Why would I want a RISC-V chip over something like an ESP32 or PICO?
- snvzz 3y ago>What is special about RISC-V? It is the best ISA around, and it is an open standard with wide industry support. >over something like an ESP32 Espressif has stated intend to transition to RISC-V entirely. Newer ESP32 like the C3 and C6 are already based on RISC-V.
