The ESPuno Pi Zero, is a pin compatible Raspberry Pi ESP32 Controller and Emulator in a single board.

The Raspberry Pi GPIO’s are controlled and driven from the ESP32-C6 and GPIO Expander, so bringing Raspberry Pi PiHat’s and Breakout boards to the Arduino Embedded controller world.

Top Level Devices

The purpose of ESPuno Pi Zero, is to provide a very compact board which includes the below main features:

Espressif ESP32-C6
- WiFi, Bluetooth, Zigbee and Thread
PCA9671
- 16 Port GPIO Expander. 5V Tolerant.
TI TMP102 -Digital Temperature
Siproin SSP9481 -5 to 60V DC SMPS for wide ranging power input, providing a stable 5V
OnSemi NCP167BMX330 -5V to 3V3 DC SMPS
EEPROM P24C64C -64Kbit storage -Two of these are included, one for ATGM336H and one for the ESP32-C6.

Features

Radio and U.FL

ESPRanger main MCU is the ESP32-C6 which includes a powerful radio module, opening up a range of IoT applications that include:

Wi-Fi 6

2.4 GHz (2400 ~ 2483.5 MHz)
802.11ax (20 MHz bandwidth)
802.11b/g/n (20/40 MHz bandwidth)
CE Max EIRP 19.81 dBm

Bluetooth

2.4 GHz (2400 ~ 2483.5 MHz)
Bluetooth LE
Bluetooth 5.3
Bluetooth Mesh
CE Max EIRP 18.46 dBm

Thread 1.4

2.4 GHz (2405 ~ 2480 MHz)
802.15.4
Thread Mesh
CE Max EIRP 10.29 dBm

Zigbee 3.0
