The module can be specified into a production run without planning a near-term migration to a replacement part. ## Memory and core — the design budget The module integrates an ESP32-S3R8 IC with 8 MB flash and 384 kB ROM on-chip. The 8 MB flash is the non-volatile store for application code, OTA update staging, and file-system data — enough headroom for a full RTOS stack with WiFi and BLE stacks plus a moderate application layer. The 384 kB ROM holds bootloader and core library routines; the usable RAM for the application is the internal SRAM of the ESP32-S3 die, not separately listed here but typically 512 kB in this family. Budget the firmware image size against the 8 MB flash ceiling before layout freeze. ## Wireless link budget — 20.5 dBm and -104.5 dBm sensitivity Transmit power is rated at 20.5 dBm — roughly 112 mW ERP at the antenna port. This is a high-power configuration for a 2.4 GHz module, giving roughly 3–5 dB more link margin than the typical 18 dBm parts. The receiver sensitivity of -104.5 dBm at the lowest data rate means the module can decode a signal at about -104.5 dBm, which translates to a usable range of several hundred metres line-of-sight in open air. The antenna is a PCB trace — no external antenna connector or U.FL port on this variant. The trace antenna is tuned for the module's ground plane and enclosure; if the final product uses a metal housing or a different board stack-up, the antenna resonance shifts and the radiated power drops. Plan for a radiated-spurious and TRP/TRX test in the final enclosure. ## Supply rails and current draw The receiving current is 97 mA to 100 mA; transmitting current jumps to 273 mA to 330 mA depending on the output power setting and the PHY rate. The 330 mA peak at 3.3 V is about 1.1 W peak dissipation — the 41-SMD module's copper pads and the board's thermal vias must sink that heat in still air. The 3.3 V rail should be rated for at least 500 mA to cover the module plus any external pull-ups or level shifters. A low-dropout regulator with a 3.3 V output and 500 mA capability is the standard choice; a switching regulator adds efficiency but injects ripple that can desensitise the receiver if the switching frequency falls in the 2.4 GHz band or its harmonics. ## Temperature grade and environment This covers outdoor enclosures, engine-bay-adjacent installations, and unheated warehouse environments. The module is not qualified for the full automotive -40°C to 125°C range; if the end product sees sustained junction temperatures above 85°C, the flash retention and the crystal oscillator accuracy degrade. The ESP32-S3-MINI-1-N8 is an active Espressif product. The module ships in Strip packaging — the standard carrier for SMD modules. The 41-SMD Module footprint is a castellated-edge land-grid array; the solder profile follows the standard JEDEC J-STD-020 for a moisture-sensitive component.","metaTitle":"ESP32-S3-MINI-1-N8 Espressif Systems RF Module, 8MB Flash","metaDescription":"Active Espressif ESP32-S3-MINI-1-N8 module with 8MB Flash, 2.4GHz WiFi & BLE 5.0, 20.5dBm Tx power, -40~85°C.
