Description The ESP32-C3 Mini Development Board is an entry-level development board based on ESP32-C3-MINI-1, a module named for its small size. This board integrates complete Wi-Fi and Bluetooth® LE functions. Most of the I/O pins on the ESP32-C3-MINI-1 module are broken out to the pin headers on both sides of this board for easy interfacing. Developers can either connect peripherals with jumper wires or mount ESP32-C3-DevKitM-1 on a breadboard. Features WiFi IEEE 802.11 b/g/n-compliant Supports 20 MHz, 40 MHz bandwidth in 2.4GHz band 1T1R mode with data rate up to 150 Mbps Wi-Fi Multimedia (WMM) TX/RX A-MPDU, TX/RX A-MSDU Immediate Block ACK Fragmentation and defragmentation Transmit opportunity (TXOP) Automatic Beacon monitoring (hardware TSF) 4 × virtual Wi-Fi interfaces Simultaneous support for Infrastructure BSS in Station mode, SoftAP mode, Station + SoftAP mode, and promiscuous mode. Note that when ESP32-C3 family scans in Station mode, the SoftAP channel will change along with the Station channel Antenna diversity 802.11mc FTM Bluetooth Bluetooth LE: Bluetooth 5, Bluetooth mesh Speed: 125 Kbps, 500 Kbps, 1 Mbps, 2 Mbps Advertising extensions Multiple advertisement sets Channel selection algorithm #2 CPU and Memory 32-bit RISC-V single-core processor, up to 160MHz 384 KB ROM 400 KB SRAM (16 KB for cache) 8 KB SRAM in RTC Embedded flash (see details in Chapter 1 Family Member Comparison) SPI, Dual SPI, Quad SPI, and QPI interfaces that allow connection to multiple external flash Advanced Peripheral Interfaces 22 × programmable GPIOs Digital interfaces: 3 × SPI 2 × UART 1 × I2C 1 × I2S Remote control peripheral, with 2 transmit channels and 2 receive channels LED PWM controller, with up to 6 channels Full-speed USB Serial/JTAG controller General DMA controller (GDMA), with 3 transmit channels and 3 receive channels 1 × TWAI® controller (compatible with ISO 11898-1) Analog interfaces: 2 × 12-bit SAR ADCs, up to 6 channels 1 × temperature sensor Timers: 2 × 54-bit general-purpose timers 3 × watchdog timers 1 × 52-bit system timer Low Power Management Power Management Unit with four power modes Security Secure boot Flash encryption • 4096-bit OTP, up to 1792 bits for users • Cryptographic hardware acceleration: – AES-128/256 (FIPS PUB 197) Documents User Guide Datasheet (ESP32-C3 Mini Development Board) Datasheet (ESP32-C3 Mini Module) Schematic PCB Layout Board Dimensions
