ESPKnack LoRa GNSS IMU RS485 STEM SDK Board

Hello my name is Dave Williams and welcome to my DitroniX channel video in order to visualise the many STEM Electronic projects which I support to people Worldwide.

In this short video, you will see some snippets of the new ESPKnack (ESP Knack), which is successfully launching via Kickstarter in January 2026.

[About]
ESPKnack is a compact and powerful STEM Community board which is designed for LoRa (Long Range wireless communication), with Galvanically Isolated Inputs and Outputs - including 4-20mA Current Loop, RS485 and an Accurate Real Time Clock.

[Features] - The key ingredients (Prelim):

The ESPKnack , provides a very compact board which includes the below main features:

* Espressif ESP32-C6 U.FL (WiFi, Bluetooth, Zigbee and Thread)
* EByte E22-900MM22S LoRa (LoRaWAN, SX1262 module for 868MHz through to 915MHz)
* Chipanalog CA-IS2092 (Industry Standard Galvanic Isolated RS-485 interface)
* RTC DS3231SN (Accurate RTC with optional Battery Backup)
* 4-20mA Current Loop (HCNR200-500E - Galvanic Isolation)
* ADC ADS1115 (16bit 4 Channels - Useable Inputs 3)
* TI TMP102 (Digital Temperature Board Sensor)
* FET 2N7002DW (PWM/GPIO Output Galvanic Isolation)
* Relays SRD-05VDC-SL-CC (10A 250VAC or 10A 30V DC SPDT - NO/NC - Galvanically Isolated Contacts)
* Siproin SSP9481 (5 to 60V DC SMPS for wide ranging power input, providing a stable 5V)
* 24 V DC Output
* OnSemi NCP167BMX330 (5V to 3V3 DC SMPS)
* EEPROM P24C64C (64Kbit storage)
* STEM SDK Board or can be mounted in DIN Enclosure with optional Display Interface
