Product details

Overview

AMS002-E03 from ACKme Networks is a TruConnect-enabled Bluetooth Low Energy evaluation board built around the surface-mount AMS002 'Bobcat' module. It provides USB-powered operation, dual-user LEDs and buttons, 3.3V peripheral header (UART/I²C), dual 11-pin breakout headers, and integrated current measurement with sub-mA accuracy for BLE firmware validation and sensor interface prototyping.

For engineers reviewing the AMS002-E03 datasheet, AMS002-E03 pinout, AMS002-E03 application, or AMS002-E03 equivalent, this page delivers verified hardware interface details, UART configuration guidance, GPIO mapping, current measurement methodology, and TruConnect command-mode interaction specifics required for rapid BLE integration and low-power wireless sensor development.

Technical Context

The AMS002-E03 implements the 'Bream' reference design for ACKme's AMS00x 'Bobcat' family, integrating an FTDI FT230XQ USB-to-UART bridge and LM1117MP-3.3 LDO to deliver stable 3.3V power to the AMS002 module. It supports two UART interfaces - User UART (GPIO2/TX, GPIO5/RX) and Programming UART (PROG_TX/PROG_RX) - selectable via physical switch SW1.

Hardware features include on-board current monitoring via MAX4376FAUK+ current-sense amplifier (I = V/100 scaling), isolation jumpers for ultra-low-power testing, and configurable GPIOs mapped to expansion headers H1, H6, H7, and H14 per Appendix B schematics. The board boots TruConnect v2.0.0.4 in human-command mode by default and supports factory reset via hardware pin hold or remote command.

Key Specifications

Parameter	Value and Actual Design Meaning
Form Factor	Evaluation board for AMS002 'Bobcat' BLE module - non-removable surface-mount implementation.
Power Input	USB 5V only; onboard LM1117MP-3.3 generates regulated 3.3V for DUT and peripherals.
Current Measurement	Integrated MAX4376FAUK+ circuit with I = V/100 scaling - enables oscilloscope-based dynamic current profiling down to ~1mA resolution.
UART Interface	FT230XQ USB-UART bridge; supports 115200 baud default; USER/PROG/Off switch (SW1) controls UART routing to AMS002 pins.
Expansion Headers	H1 (20-pin): full AMS002 GPIO mapping; H6/H7 (11-pin each): breakout of UART/I²C/power; H14 (16-pin): peripheral interface with UART/I²C/GPIO.
Firmware	Preloaded TruConnect v2.0.0.4 - supports COMMAND mode (configurable human/machine), STREAM mode (transparent serial tunnel), and BLE peripheral/central roles.

FAQ

What is the AMS002-E03 and how does it differ from AMS001-E03?

The AMS002-E03 is ACKme Networks' 'Bream' evaluation board pre-populated with the AMS002 'Bobcat' BLE module, while AMS001-E03 uses the AMS001 variant. Both share identical board layout, header pinouts, and TruConnect firmware behavior per the AMS00x-E03 Evaluation Guide. Differences are internal to the module IC - AMS002 integrates updated radio calibration and memory configuration but maintains full hardware and software compatibility with AMS001-E03 on the same board.

How do I configure the AMS002-E03 for UART communication with my PC?

Set the UART_SEL switch (SW1) to the USER position, connect via micro-USB, and install FTDI drivers if not auto-detected. Use Tera Term (Windows) or CoolTerm (macOS) at 115200 baud, 8N1, CR+LF transmit. Press Enter to confirm TruConnect responds with "Ready >". The AMS002-E03 exposes GPIO2 (TX) and GPIO5 (RX) as the default User UART interface routed through the FT230XQ bridge.

Can the AMS002-E03 measure sleep-mode current accurately?

No - the onboard current measurement circuit (MAX4376FAUK+) provides sub-milliamp resolution but is unsuitable for µA-range sleep current. For ultra-low-power validation, disconnect the PWR_LINK jumper and insert an external ammeter in series with the VDD_DUT net (H7 Pin 21). This bypasses the sense amplifier and allows direct measurement of AMS002-E03's deep-sleep quiescent current.

What GPIOs are exposed on the AMS002-E03 peripheral header?

The AMS002-E03 peripheral header (H14) exposes GPIO2 (USER_TX), GPIO5 (USER_RX), GPIO3 (USER_RTS), GPIO4 (USER_CTS), I²C_SCL, I²C_SDA, VDD_3V3, and GND. These pins are preconfigured in TruConnect for UART and I²C operation and can be reassigned via 'gfu' commands - e.g., 'gfu 9 mode_sel' configures GPIO9 as mode-select input.

Does the AMS002-E03 support firmware updates or custom builds?

Yes - the AMS002-E03 supports firmware updates via its dedicated Programming UART (PROG_TX/PROG_RX pins on H1), accessible when SW1 is set to PROG. ACKme provides TruConnect SDK and build tools; custom firmware binaries can be flashed using the 'flash' command in TruConnect's programming mode. Factory settings and variables persist across updates unless explicitly erased with 'fac'.
