The article claims that the ESP32 costs $5. The reality is around half of that for the MCU, and around $3 for pre certified modules including crystal, PCB antenna or UF-L connector. So it's really affordable. Espressif has also launched a new ESP32C3 based on RISC-V, with modules priced at around $2.

ESP32C3 has great Rust support too.

That's the development unit price. ESP's MCUs have amazing value when you buy in bulk.

that second core is worth its weight in gold cant wait until they can make a dual-core risc-v but p.happy on the -s3

  Dual core RISC-V? Presenting ESP32-C6: It consists of a high-performance (HP) 32-bit RISC-V processor, which can be clocked up to 160 MHz, and a low-power (LP) 32-bit RISC-V processor, which can be clocked up to 20 MHz. It has a 320KB ROM, a 512KB SRAM, and works with external flash. It comes with 30 (QFN40) or 22 (QFN32) programmable GPIOs, with support for SPI, UART, I2C, I2S, RMT, TWAI, PWM, SDIO, Motor Control PWM. It also packs a 12-bit ADC and a temperature sensor. https://www.espressif.com/en/products/socs/esp32-c6 https://www.espressif.com/en/products/socs/esp32-c6 [The High Performance] CPU . . . has 4-stage, in-order, scalar pipeline optimized for area, power and performance. CPU core complex has a debug module (DM), interrupt-controller (INTC), core local interrupts (CLINT) and system bus (SYS BUS) interfaces for memory and peripheral access. The ESP32-C6 Low-Power CPU (LP CPU) . . . features ultra-low power consumption and has a 2 stage, in-order, and scalar pipeline.

    oh sweet i didnt realize there was a module out https://www.mouser.com/ProductDetail/Espressif-Systems/ESP32-C6-WROOM-1-N4 https://www.mouser.com/ProductDetail/Espressif-Systems/ESP32... i prefer using dual-core designs over one uC for WiFi + one uC for realtime UI + TFT screens, so much cleaner and less hardware to worry about literally porting the design i'm working on rn to that one :) ty!
