Parameter Min Typical Max Units
SPI Serial Clock Frequency - 2 8.8 MHz ()
UART Serial Clock Frequency 80 115,200 5,000,000 Baud
Parameter Max Units
802.11 Max Data Rate 150 Mbps
Bluetooth HCI Max Data Rate 4 Mbps
Note: Actual radio throughput is dependent on a number of factors including antenna type, operating environment, line of sight, and electromagnetic interference.
PCB Length: 2.00 in. (5.08 cm)
PCB Width: 0.80 in. (2.03 cm)
Note: Dimensions do not include the length of the Pmod header pins. The ESP32 antenna overhangs the PCB by 1/4“.
The Pmod ESP32 integrates WiFi and Bluetooth 4.2 solutions on a single chip along with dual high performance cores and several
peripherals. The ESP32 possesses the ability to connect to an existing WiFi network or broadcast its own as an access point.
