Beijing-based embedded hardware specialist AnalogLamb has announced three new low-cost entries in its Polos family of development boards, all powered by RISC-V microcontrollers from WCH Electronics — and with prices starting at $1.99.
“Polos CH32Vxx RISC-V Breakout Boards are interconnectivity MCU [Microcontroller Unit] boards based on 32-bit RISC-V core,” AnalogLamb explains in its product announcement, brought to our attention by Linux Gizmos, “with hardware stack area and fast interrupt entry. Compared with standard RISC-V, the interrupt response speed is greatly improved.”
