nRF52 Module With Battery Power

PN: NRFMOD-001, Last updated: December 2022 (Rev A)

nRF52 pcb design example

This Bluetooth module is based on the nRF52 WLCSP fine-pitch BGA package. Includes an EEPROM, programming header, I/O header, batter connector, and power/battery management. USB charging is not included at this time.

Major components include:
  • nRF52840 (WLCSP)
  • TPS70933DBVR
  • FR015L3EZ
  • PCF8523TK
  • CAT24C512WI-GT3

Dual ADC Module

PN: ADCEX-001, Last updated: December 2022 (Rev A)


This ADC module includes a rad-hard power regulator from Intersil and two ADCs: 1 isolated ADC and 1 non-isolated ADC. Input signals for the ADC and isolated +5V power are provided through 3 SMA connectors. An I/O pin header is included for access input/output data and programming the non-isolated ADC.

Major components include:
  • ADC128S102CIMTX
  • AMC1203BPSA

USB to UART Bridge

PN: USBUART-001, Last updated: January 2023 (Rev A)


This module provides USB-to-UART conversion in a small form factor. The device includes additional ESD protection on the input and output sides of the device for added reliability. Additional protection could be implemented with an enclosure and a chassis guard ring applied to the board edge.

Major components include:
  • CP2102

USB Charger Module

PN: USBCHG-001, Last updated: January 2023 (Rev A)


This 2-port USB charger module operates at 12 V input with maximum power output of 15 W at 5 V (3 A maximum current) per port. This device uses edge connections for a pluggable interface, although it could be modified to include a through-hole connection to a pin interface or flying leads.

Major components include:
  • LM73606
  • TPS2549
