@gorankg Ono jes, ako zaista bude 4$ onda je cena definitivno najbolja.
Ja sam prvo pomislio na konkurenciju ovog tipa:
STM32F411
https://www.aliexpress.com/item/4000282242626.html
Ili još moćniji sa H serijom:
STM32H750xB devices are based on the high-performance Arm® Cortex®-M7 32-bit RISC core operating at up to 480 MHz. The Cortex® -M7 core features a floating point unit (FPU) which supports Arm® double-precision (IEEE 754 compliant) and single-precision data-processing instructions and data types. STM32H750xB devices support a full set of DSP instructions and a memory protection unit (MPU) to enhance application security. STM32H750xB devices incorporate high-speed embedded memories with a Flash memory of 128 Kbytes, up to 1 Mbyte of RAM (including 192 Kbytes of TCM RAM, up to 864 Kbytes of user SRAM and 4 Kbytes of backup SRAM)

Ovde mi je zanimljivo koliko RAM-a imaju ovi STM32H750...
Ipak je verzija sa dual-core MCU skuplja, STM32H743xB, tako da je ovaj RPy Pico što se tiče cene best-buy. Sa druge strane, Cortex M0 i Cortex M4 su ipak prilično različiti.
