It carries 2 MB of embedded flash, 128 kB ROM, and 320 kB SRAM on-chip, which simplifies BOM by eliminating an external flash die for many IoT applications. ## Radio performance and interface set Receiver sensitivity is rated at -97 dBm, which is typical for a 2.4 GHz OFDM receiver at the lowest data rate — this sets the link budget for a given output power and path loss. The transmit output reaches 19.5 dBm, above the common 18 dBm ceiling, extending range in high-interference environments. Current draw in receive mode is 63 mA to 68 mA; transmit current ranges from 160 mA to 310 mA depending on output power setting. The serial interface set includes ADC, GPIO, I²C, I²S, SPI, PWM, UART, and USB — enough for sensor aggregation, display driving, and direct USB connectivity without an external bridge. Housed in a 56-VFQFN Exposed Pad package, the ESP32-S2FH2 is a surface-mount device. The antenna is not included on the package — an external antenna (PCB trace, chip, or SMA-connected) must be added to the RF pin. The 56-pin QFN pitch is 0.5 mm; a 4-layer PCB with a solid ground plane under the RF section is the standard layout practice.","metaTitle":"ESP32-S2FH2 Espressif WiFi IC, 2.4GHz, 150Mbps","metaDescription":"ESP32-S2FH2 WiFi SoC, 2.4GHz 802.11b/g/n, 150Mbps, 2MB Flash, 320KB SRAM, -40 to 105°C, Active.
