ESP32-C3 is a multi-mode SoC with WiFi and BLE radios and RISC-V core. This device is manufactured by Expressif in Shanghai. ESP32 is a famous product line for low-cost WiFi/BLE dual mode IoT SoC. The early models are designed with Xtensa LX soft-core. Now Expressif released a RISC-V based version. Its key features: Single core RISC-V SoC running up to 160MHz with 4 level pipelines Built-in 400KB SRAM (16KB cache) 384KB ROM  SPI/Dual SPI/Quad SPI/QPI interfaces to external memories Broad temperature range RSA3072 based security boot, and AES128/XTS256 code protection Digital signature and HMAC modules TRNG True random number generator IEEE802.11 b/g/n 2.4GHz, 20MHz/40MHz bandwidth 1T1R, up to 150Mbps BLE 5 / BLE mesh on 125K/500K/1M/2Mbps 21dBm TX 22 GPIO 3x SPI 2x UART 1x I2C 1x I2S IR transmitter, 2 TX/2RX 6 channel LED PWM Full speed USB serial/JTAG GDMA 1x TWAI for CAN2.06 channel 1x temperature sensor 2x 54bit GP timers 3x watchdog timers 1x analog watchdog timer 1x 52bit syst...

W801 is a WiFi/BLE IoT SoC manufactured by Winner Micro, which is based in Beijing, China. It has rich on-chip peripherals. The key features are: 2.4GHz IEEE802.11b/g/n  Bluetooth/BLE 4.2 dual mode Integrated 32bit C-Sky V2 core General Purpose IO: GPIO/ADC Rich communication interfaces: UART/SPI/I2C Special interface: I2S/7816/SDIO UI interface: LCD/Touch sensor Memory interface: PSRAM Security module: TEE with hardware encryption algorithms Built-in DSP Built-in FPU Code protection 2MB XIP flash memory with code encryption, signature, secure debug, secure OTA GCC support PS: C-Sky V1 was M-core from Motorola semiconductors, and C-Sky V2 was upgraded and revised. Assessment: XIP flash may have some restriction on execution speed and power consumptions. Some time critial code has to run in the RAM ADC precision is low and sampling rate is low. Lack of documentations and supports, although it is quite cheap. A complete SDK/toolchain is ready for OSHW community, but it is helpful for...
